/*
			COI 14-gta

	All the molecules belong to one of the 24 equivalence classes, based on what we can obtain 
by performing the algorithm.

	We can represent A, C, G, T as permutations which will help us generate the mutations.
	
    All we're left with is checking if the permutations are equivalent and print the adjacency matrix.
