[GAP Forum] Contain a fixed subgroup

[Mr. Sorouhesh]

Dear Friends,

Trough working on the following problem:

http://math.stackexchange.com/q/168180

you can see, the questioner defined a* new operation *on CyclicGroup(7) ,
to find inverse elements and search some properties in the group.

This crossed my mind with this question if we can define a new well-defined
operation on a certain set ,in GAP, to do for example what he did in the
above question?

Best
