[GAP Forum] CanonicalRightCosetElements on a rightransversal of a subgroup of a dihedral group

[Pierre-Alain BOURDIL]

Dear GAP Forum,

i have an issue related to a right coset representative on a dihedral 
group. Is there a explanation for such an error ?

gap> L:=DihedralGroup(IsPermGroup,10);;
gap> S25:=Stabilizer(L,[2,5],OnSets);;
gap> RT25:=RightTransversal(L,S25);;
gap> List(RT25);
[ (), (1,5,4,3,2), (1,4,2,5,3), (1,2)(3,5), (1,3,5,2,4) ]
gap> CanonicalRightCosetElement(RT25,(1,4,2,5,3));
Error, no method found! For debugging hints type ?Recovery from 
NoMethodFound
Error, no 1st choice method found for `CanonicalRightCosetElement' on 2 
arguments called from

you can 'quit;' to quit to outer loop, or
you can 'return;' to continue
