 Encyclopedia: Modular arithmetic   (Site not responding. Last check: 2007-10-20)
In group theory, a cyclic group is a group that can be generated by a single element, in the sense that the group has an element a (called a generator of the group) such that, when written multiplicatively, every element of the group is a power of a.
Group theory is that branch of mathematics concerned with the study of groups.
In mathematics, the multiplicative group of integers modulo n is the group defined by multiplication of the units (that is, the numbers relatively prime to) in the ring for a given integer.

The mathematical concept of a group is one of the fundamental notions of modern algebra.
Groups underlie the other algebraic structures such as fields and vector spaces and are also important tools for studying symmetry in all its forms.

 The Math Forum - Math Library - Group Theory   (Site not responding. Last check: 2007-10-20)
Group theory can be considered the study of symmetry: the collection of symmetries of some object preserving some of its structure forms a group; in some sense all groups arise this way.
Group theory takes an abstract approach, dealing with many mathematical systems at once and requiring only that a mathematical system obey a few simple rules, seeking then to find properties common to all systems that obey these few rules.

 math lessons - Group action
A permutation representation of a group G is almost the same thing: formally it may be described as a group representation of G by permutation matrices, and is usually considered in the finite-dimensional case — it is the same as a group action of G on an ordered basis of a vector space.
The automorphism group of a vector space (or graph, or group, or ring...) acts on the vector space (or set of vertices of the graph, or group, or ring...).
A group action is then nothing but a functor from G to the category of sets, and a group representation is a functor from G to the category of vector spaces.

 BACKGROUND
Note that the growth rate of the free metabelian group of rank 2 should be strictly less than 3 (which is the growth rate of the free group of rank 2) since a free metabelian group is not free.
This is the case, in particular, with the word as well as the conjugacy problem for a given finitely presented group and with the problem of isomorphism to a given finitely presented group.
The automorphism group of a free metabelian group of finite rank is known to be finitely generated unless the rank equals 3 -- see [S.Bachmuth, H.Mochizuki, Aut(F) \to Aut(F/F") is surjective for free group F of rank \geq 4, Trans.

 R devel archive: Re: [Rd] S4 group "Math", "getGr
The behavior of group generics and of the basic functions, such as those in the Math group, differs.
First, functions such as "log", "sin", and their peers are not generic functions by default in R. Second, defining methods for the group generic does not automatically turn the members of the group into generic functions.
But the implication is that code wishing to define methods for the group generic needs to ensure that all the relevant group members are set to be generic functions from the group.

 Honest Open Logical Debate on math reform - release = group forms
Palo Alto, Calif. -- "Stop Fuzzy Math," was the phrase on the lips of approximately 25 Palo Alto Unified School District parents who met Feb. 13 in the Stanford home of Joseph and Laurel Lipsick.
The bad news, hidden behind all these professional-educator "buzz words," say HOLD members, is the fact that as the "Mathematics Framework" has been implemented in the Palo Alto district in recent years, the computational skills of students have declined.
In addition, although HOLD has taken no position on the June 1995 local school-bond election, Evers pointed out, "The school-bond election heightens interest in the public schools and what is going on in them.
