Isomorphic means isomorphic as groups (not as permutation group). In particular when he says "Problem: determine all groups isomorphic to a given group $G$", it more or less means "classify all (faithful) actions of $G$ [the underlying group, in the modern sense]". | |

| Sep 3, 2017 at 21:52 | comment | added | David Roberts♦ | People were still using isomorphism onto and isomorphism into for surjective resp. injective homomorphisms, for far too long (IMHO). I've always found this weird, but I guess they were just not up to date with the change terminology. | |
