The group structure of G plays no role in the definition

The group structure of G plays no role in the definition of a G-module. For any set , D.J.S. Robinson, A Course in the Theory of Groups, 2d Edition, p. 131, speaks of a -module as being an abelian group with operator domain . Perhaps It might be better to start by defining a -module for a set and then say that a G-module is exactly a -module with = G ? Marvoir (talk) 07:48, 10 August 2021 (UTC)[reply]
