Dear GAP people,
let me start with a little puzzle: Which of the following commands
behaves differently?
AllIrredSolMatrixGroups
AllIrreducibleSolubleMatrixGroups
AllIrreducibleSolvableGroups
AllIrreducibleSolvableMatrixGroups
For a long time I have been thinking that they all were synonyms. Until
recently, I observed that AllIrreducibleSolvableGroups is different. It
takes slightly different arguments (Characteristic instead of Field) and
has a limited range. For instance:
AllIrreducibleSolvableGroups(Dimension,8,Characteristic,2);
#W AllIrreducibleSolvableGroups: n = 8 outside range of library
Error, all Dimension arguments outside range of library
AllIrreducibleSolvableMatrixGroups(Dimension,8,Field,GF(2)); #works
Now every time I want to list matrix groups I have to rethink what the
"correct" command was. I can't think of a situation where
AllIrreducibleSolvableGroups is superior to the other commands.
So my suggestion is to remove this function. It would also help me
memorizing to have just a single command instead of many synonyms (this
also improves tab-completion on the command line).
Best wishes,
Benjamin
