Right now recognition methods take two arguments:
riandG. ButGis always identical toGrp(ri). Alas, not everyone will know this, e.g. I am re-discovering this every time I start digging into recog again. This can be very confusing ("why are both these groups around? Is there any subtle difference????"). One could solve that by trying to document this, but I think it is much better to just remove the second argument.This is incomplete, a lot more needs to be changed in methods. This can only be partially automated with classical scripts (and I don't trust AI to do this), but it's actually not hard to do. Alas: I'd like to defer this until after merging PR #330 (and perhaps a few others, to minimize conflicts for those).
