it seems like with the latest Mathematica version, there is alsways a warning Part::pkspec1 when doing Start[...]. This is due to line 450 in Package/GroupTheory/grouptheory.m, which says:
Code: Select all
Off[Part::"pspec"];
Generator[group,dyn][a__Integer]=Normal[RepMatrices[SusynoForm[group],dyn]][[a]];
On[Part::"pspec"];
Code: Select all
Off[Part::"pkspec1"];
Off[Part::"pspec"];
Generator[group,dyn][a__Integer]=Normal[RepMatrices[SusynoForm[group],dyn]][[a]];
On[Part::"pspec"];
On[Part::"pkspec1"];
cheers,
