If H is another group object in C, a morphism f:G→H is a morphism of group objects if it commutes with the three structure morphisms; as is standard for sets and true generally (again by Lemma 7.7), it is enough to check 𝜇. Thus we form the category textit Gp(C) of all group objects in C; one important example is textit Gp( textit Ho).
