Description

Given two FinSets A, B is there some computation that creates the set of all functions in Hom(A, B)? For example if A has 5 elements and B has 2, there should be 32 functions in the set f: A->B.

Contributor guide

Research direction
Implement the exponential object in FinSet by constructing the set of all functions between two finite sets. Research existing category theory implementations and the FinSet type in Catlab.
