Let T be a Grothendieck topology, Ab the category of abelian groups, and . the category of Ab-valued sheaves on T. It is known that is an abelian A B5 category with a set of generators [2, Theorem 1.6(i), p. 30] and, hence, has injective envelopes [10, Theorem 3.2, p. 89]. Consider an object F of .
