Abstract
The biset category C of finite groups is the category defined as follows: The objects of C are finite groups. If G and H are finite groups, then HomC(G, H) = B(H, G). If G, H,and K are finite groups, then the composition v º u of the morphism u ∈ HomC(G, H) and the morphism v ∈ HomC(H, K) is equal to v × H u. For any finite group G, the identity morphism of G in C is equal to [Id G ].
