WebIn mathematics, the free group F S over a given set S consists of all words that can be built from members of S, considering two words to be different unless their equality follows from the group axioms (e.g. st = suu −1 t, but s ≠ t −1 for s,t,u ∈ S).The members of S are called generators of F S, and the number of generators is the rank of the free group. .

WebA more restrictive statement of the definition would be that G is a generator if, whenever f and g are both morphisms from X to Y, there exists a morphism h from G to X, such that f=g iff hf=hg.
