A section of a group G is a quotient of a subgroup, viz. K normal in H subgroup of G, the section is H/K.

Does anyone know if there is a more-or-less standard terminology not just for the section-up-to-isomorphism-of-the-group-H/K, but for the "instantiated" or maybe "concrete" section, e.g. the pair (K,H)?
