		Enumerations of finite sets obviously require that either non-injectivity or partiality is accepted, and in contexts where finite sets may appear one or both of these are inevitably present.

		If a set is enumerable it will have an uncountable infinity of different enumerations, except in the degenerate cases of the empty set or (depending on the precise definition) sets with one element.

		They are a model of the axioms consisting of the axioms of set theory with the axiom of infinity replaced by its negation, thus proving that the axiom of infinity is not a consequence of the other axioms of set theory.

		The abstract tree contains the whole set of extensions ({8n+5} or 5[8] integers) as its root and follows the partitioning of the integers as it develops all possible left descents (in the binary tree) by separating the s-descendant subset, the b-descendant subset, and the leaf subset at every level of its development.
		In this work, finite sums were calculated to confirm the convergence of infinite sums and measure the coverage of the integers by the predecessor tree.
		sieve -- A process by which a set (here, the odd integers) may be repeatedly scanned to mark those satisfying a certain property (here, inclusion in one of the infinite instantiations of a left descent assembly) and identify new scanning elements (here a new left descent assembly) for use in repetition of the process.

	Peter Suber, "Infinite Sets"
		Set A is a proper subset of set B iff all the members of A are also members of B, but not all the members of B are members of A. Notation.
		Two sets can be put into one-to-one correspondence iff their members can be paired off such that each member of the first set has exactly one counterpart in the second set, and each member of the second set has exactly one counterpart in the first set.
		Together with the trivial truth that no finite set can be put into one-to-one correspondence with any of its proper subsets, this theorem establishes the important result that all and only infinite sets possess the property that they can be put into one-to-one correspondence with at least one of their proper subsets.

	Uncountable set Summary
		So any two finite sets with the same number of elements have the same cardinality, and clearly any two finite sets with the same cardinality can be placed in one-to-one correspondence with each other.
		Not all uncountable sets have the same size; the sizes of infinite sets are analyzed with the theory of cardinal numbers.
		The diagonalization proof technique can also be used to show that several other sets are uncountable as well, for instance the set of all infinite sequences of natural numbers (and even the set of all infinite sequences consisting only of zeros and ones) and the set of all subsets of natural numbers.

	The Finite Nature Hypothesis of Edward Fredkin
		The model of a finite set of information represented by scalar values, transformed to a new and equally finite set of information, is to be found in the programming processes of an ordinary computer.
		Fredkin concludes: "Given Finite Nature, what we have at the bottom is a Cellular Automaton of some kind." And, because "Automata, Cellular Automata and Finite State Machines are all forms of computers," this is to say that at the bottom of the physics of the natural world, we have a computer of some kind.
		Finite Nature means that our world operates as though it were the product of a computing system, and Fredkin sees that this is because our universe is an artifact produced by a computer of some sort.

	The Diagonal Method on Finite Binary Strings
		Georg Cantor developed the diagonal method to study infinite sets, but to understand the diagonal method, it is best to begin by applying the technique to finite sets.
		We can shuffle this set and, in every case, the diagonal method will produce a three character binary string that is not in the first three positions of the set.
		However, it should be clear that when performed on the set of Reals, the absurdity returned by the diagonal method is of the same form as the Liar's Paradox.

	Finite Geometries?
		Fano's work in the area of finite geometry included the discussion of a 3-dimensional finite geometry which consisted of 15 points, 35 lines, and 15 planes where each line had 3 points on it and each plane had 7 points.
		It turns out that for a finite projective plane with 17 points on each line, there are currently 13 known such planes, no pair of which are isomorphic.
		In particular, the structure of finite geometries is often used in the branch of statistics devoted to the design of experiments.

	Finite Automata
		In a stochastic finite automaton (SFA), f(q,a) and h(q) are random functions and Pr(f(q,a)q,a) and Pr(h(q)) define the state transition and output probabilities respectively.
		In a probabilistic finite automata (PFA), the output in state q is a random function of q, and the state following q is a deterministic function of q and the output in q.
		PFSA is a PFA in which each state in Q has a unique label corresponding to a sequence (string) of outputs and, moreover, the label for f(q,h(q)) is a suffix of the sequence defined by concatenating the output h(q) to the label for q.

	Basics of Automata Theory
		FSMs are abstract machines, consisting of a set of states (set Q), set of input events (set I), a set of output events (set Z) and a state transition function.
		Inputs: finite set of input, depending on the number of floors the elevator is able to access.
		They can operate on languages with a finite number of words (standard case), an infinite number of words (Rabin automata, Bïrche automata), various types of trees, and in hardware circuits, where the input, the state and the output are bit vectors of a fixed size.

		Analysis needed the set theory of Cantor, it could not afford to limit itself to intuitionist style mathematics in the spirit of Kronecker.

	QUANTUM SET THEORY INTRO
		To continue from simply counting null sets, to set theory, one needs to add a concept or operation of labeling, so that a point or element of a set can be intrinsically distinguished from all others.
		In dealing with a conjectured "quantum set theory", the fundamental concepts leading to classical set theory may have to be eliminated replaced or augmented.
		So this entire subject is either a rather general matter of mathematical possibilities, or a refinement of the physics of "physical geometry", and then on a level of theoretical difficulty rivaling that of quantum gravity.

	Nielsen's First Theorem of Infinite Sets (Site not responding. Last check: 2007-10-13)
		Call your given infinite set A. Call the new created from the function f set B when you apply f to the set A. f(A) = B. Any union of countable (listable) sets result in a countable set.
		The set M is the same as the set B because we have applied f to all elements of A. Each element of mi of M is finite since the function f only returns a finite set given a finite set.
		Create a new set N with the following property: For each mi in the set M, create the element ni in the set N which lists only new elements of mi which have not appeared before from m1 to mi-1.

	Welcome to the Hotel Infinity
		Sets such as all of the counting numbers, or all of the even numbers are infinite sets.
		Our intuition and experience with finite things in the world makes us want to protest that when we pair up the members of these sets, the set without the shoe, will run out of members before the other one does.
		Although the sizes of the infinite sets of counting numbers, even numbers, odd numbers, square numbers, etc., are the same, there are other sets, the set of numbers that can be expressed as decimals, for instance, that are larger.

	Consciousness Is Finite (But I Don't Mind)
		But by consciousness being finite, I mean something stronger: that there are only finitely many lives that could possibly be lived; and that therefore free will, if it exists, must at some level be simply the selection of an element from a finite set.
		You might object that, even if there are a finite number of phone conversations that could be had, paintings that could be painted, and human lives that could be lived, the numbers are so astronomical that it would make no difference if they were infinite.
		These two classes of sets have very different properties: an infinite set can be placed in one-to-one correspondence with a proper subset of itself (think of the whole numbers and the even whole numbers), but this isn't the case for any finite set, no matter how large.
