Hi,

I get indeed:

gap> G:=CyclicGroup(4);;
gap> A:=TrivialModule(G,GF(2));;
gap> A:=TrivialGModule(G,GF(2));;
gap> A1:=AutomorphismGroup(G);;
gap> A2:=GL(1,2);;
gap> D:=DirectProduct(A1,A2);;
gap> P:=CompatiblePairs(G,A,D);;
gap> M:=ExtensionRepresentatives(G,A,P);;
gap> List(M,IdGroup);                    
[ [ 8, 2 ], [ 8, 2 ] ]
gap>   

De difference being my (and Vipul's) use of List(M,IdGroup);
And you using: List(last,IdGroup);


Yours truly


Lisette
