f: A to B and g: B to C are bijective functions. Then: 1. g o f: A to C is a bijective function. 2. The inverse relation f-1: B to A is also a bijective function. Let S be a non-empty set. Let F be the set of all bijections of S onto itself: F={f is an element of SxS| f: S to S is a bijection} Prove: (F, o) is a group.
