[GAP Forum] Failed to run AreRepsIsomorphic command.

[Hongyi Zhao]

Hi GAP team,

Based on the guidance here [1], I tried to do the following testing but failed:

gap> LoadPackage("RepnDecomp");
true
gap> g:=CyclicGroup(IsFpGroup,8);
<fp group of size 8 on the generators [ a ]>
gap> AreRepsIsomorphic(IrreducibleRepresentations(g),IrreducibleRepresentations(SmallGroup(8,1)));
Error, no method found! For debugging hints type ?Recovery from NoMethodFound
Error, no 1st choice method found for `Source' on 1 arguments at

gi:234 called from
<function "AreRepsIsomorphic">( <arguments> )
 called from read-eval loop at *stdin*:18
type 'quit;' to quit to outer loop


How to fix the above command?
