A subgroup H of a group G is termed a sub-(isomorph-normal characteristic) subgroup if there exists an ascending chain of subgroups:

H = H_0 \le H_1 \le H_2 \le \dots \le H_n = G

such that each H_i is an isomorph-normal characteristic subgroup of H_{i+1}, i.e., H_i is characteristic in H_{i+1}, and H_i is isomorph-normal in H_{i+1}: every subgroup of H_{i+1} isomorphic to H_i is normal.
