We already have
PartialOrderOfDClasses
andMaximalDClasses
; it would be nice if we had similar forL
andR
. It would be useful for my code to do with direct products, in particular.I've added methods for enumerable semigroups. I feel like it should be simple to do something clever for acting semigroups, but maybe not.
I still need to polish this PR (more manual examples and tests), so it's not ready to be merged, but I'm creating this PR to spur me to finish it, and possibly as a way to ask for advice.
