 Coset enumeration - Wikipedia, the free encyclopedia
In mathematics, coset enumeration is the problem of counting the cosets of a subgroup H of a group G given in terms of a presentation.
Coset enumeration is usually considered to be one of the fundamental problems in computational group theory.
The original algorithm for coset enumeration was invented by John Arthur Todd and H.

 Enumeration (Java 2 Platform SE v1.4.2)
An object that implements the Enumeration interface generates a series of elements, one at a time.
Methods are provided to enumerate through the elements of a vector, the keys of a hashtable, and the values in a hashtable.
Enumerations are also used to specify the input streams to a

 Introductory Note on Census Enumeration
Choice of an enumeration method is determined by a number of factors, including budgetary constraints; census laws that specify the method; the capacity to print and distribute questionnaires and other materials; other concurrent national activities; weather patterns; security of enumerators; and public attitudes.
The qualities of good enumerators are that they are able to work independently, solve problems on the spot and know when to contact supervisors for problems that arise that are outside their scope.
When enumerators are not rewarded for careful work or perceive that they will be paid regardless of their efforts to obtain responses from each household in their enumeration area, quality may suffer.

 NARA 1930 Census Microfilm Locator - Enumeration District Maps
An enumeration district, as used by the Bureau of the Census, was an area that could be covered by a single enumerator (census taker) in one census period (2-4 weeks for the 1930 census).
Enumeration districts varied in size from several city blocks in densely populated urban areas to an entire county in sparsely populated rural areas.
Enumeration district maps show the boundaries and the numbers of the census enumeration districts, which were established to help administer and control data collection.

 Enumeration Forms   (Site not responding. Last check: 2007-11-07)
While the facsimilies convey the physical layout of the documents used to enumerate the population, they are not always clear enough to actually read the questions.
Enumerator instructions for the early years — beginning with 1850 -- and general instructions included with the self-enumeration forms in the later years are also reproduced here.
However, the 1850 enumeration schedule had “format and content identical with the 1860 schedule, except that the 1850 schedule did not contain the inquiry on value of personal estate.” Text for the 1850 census questions is included.

 Enumeration and Chronology Fields (863-865)   (Site not responding. Last check: 2007-11-07)
The captions that identify the enumeration and chronology levels and the codes that define the publication pattern of the holdings are contained in the Captions and Pattern fields (853-855) that are linked to the 863-865 fields by a number in subfield $8 (Field link and sequence number).
Indicates whether the enumeration and chronology is expressed in a compressed or uncompressed (itemized) form and whether this field or a linked Textual Holdings field should be used for display purposes.
These enumeration subfields are correlated with the enumeration caption subfields $a-$h in the Captions and Pattern fields (853-855) linked to the 863-865 field, although the same subfields need not always be present.

 2001-DP11: Spans of enumeration and chronology in expressing publication patterns in the MARC 21 Holdings Format   (Site not responding. Last check: 2007-11-07)
With this method it may be possible to define spanned enumeration that embraces both continuous and restarting numbering continuity ($v).One alternative is to introduce a new subfield for ranges within the enumeration levels.
In this case the enumeration picks up the range value of 2 and is able to calculate the sequence 21-23, 24-26, and 27-29.
In extending the coding to a case with both enumeration and chronology, consideration might be given to combining the spanned chronology with the unspanned enumeration in brackets.

 Interactive Coset Enumeration
This function creates a coset enumeration process for enumerating the cosets of the subgroup H of the finitely presented group G. Note that no actual coset enumeration is started for the created coset enumeration process.
This means that a coset enumeration process P for the cosets of H in G is transformed into a coset enumeration process for the cosets of < H, w > in G, where < H, w > denotes the subgroup of G generated by H and w.
Change enumeration parameters of the coset enumeration process P. The set of parameters accepted by this function is the same as for the function CosetEnumerationProcess; see there for a description.

 Cover Pages: WS-Enumeration and WS-Transfer Published as Web Services Messaging Specifications.
It brings enumeration capabilities to the WS-* suite of specifications, enabling an application to ask for items from a list of data that is held by a Web service.
It should be emphasized that different enumerations of the same data source may produce different results; this may happen even for two enumeration contexts created concurrently by a single consumer using identical Enumerate requests.
Enumeration, in particular, is achieved though establishing a session between the data source and the requestor.

 Enumeration Types
Each enumeration literal corresponds to a distinct value of the enumeration type, and to a distinct position number.
The position number of the value of the first listed enumeration literal is zero; the position number of the value of each subsequent enumeration literal is one more than that of its predecessor in the list.
22 If an enumeration literal occurs in a context that does not otherwise suffice to determine the type of the literal, then qualification by the name of the enumeration type is one way to resolve the ambiguity (see 4.7).

 863-865 Enumeration and Chronology - General Information
A 863-865 Enumeration and Chronology field contains a description of the holdings of a bibliographic item in the collections of the reporting organization.
The captions that identify the enumeration and and chronology levels and the codes that define the publication pattern of the holdings are contained in the 853-855 Captions and Pattern field that is linked to the 863-865 field by a number in subfield
The second indicator position contains a value that indicates whether the enumeration and chronology in the field is expressed in a compressed or uncompressed (itemized) form and whether the 863-865 field or an 866-868 Textual Holdings field should be used for display purposes.

 Enums: Advanced Enumeration Ideas   (Site not responding. Last check: 2007-11-07)
Most people are familiar with enumerations as a set of unique values that can be declared in a small, simple fashion.
The general rule is to structure enumerations with the declared values first, and then any additional fields and methods after that.
Enumeration objects can only be produced inside of the enumeration itself (as one of the unique values).

In the first phase DOS will collect enumeration data for people who are issued immigrant visas and who will be admitted to the U.S. by INS as aliens lawfully admitted for permanent residence and issued Form I-551, Permanent Resident Card (also known as the “green card”).
In addition to the enumeration data that SSA needs, INS also transmits to SSA the person's alien registration number (A number) and, for aliens in the initial phase of EAE, the code “IMM” indicating the person was lawfully admitted for permanent residence.
When an enumeration record received from INS has the code “IMM,” the Numident shows an IDN code of “H” and the system issues an SSN card without a legend.

 Embedded.com - Enumeration Constants vs. Constant Objects
The crux of the problem with constant objects is that, while an enumeration constant is an rvalue, a constant object is a non-modifiable lvalue.
You can't declare an enumeration constant as static or extern.
Although you can declare an enumeration constant in local or global scope, the declaration's scope is unlikely to affect the way the compiler generates code for the constant.

 Synoptic Enumeration
Please note that it is not a list of all merely possible solutions.
Graph theory tells us that the inital number of possible solutions (enumerations of n-vertex directed acyclic graphs) are 25 for three documents (Matthew, Mark, Luke, and no other), 543 for four (the synoptics and one hypothetical document), and 29,281 for five (plus two hypothetical documents).
Clearly, it is desirable to prune the solution set into something more workable.
