Description (last modified by stumpc5)

This is still to be done, either using hard-coded data (depending on the speed), or the uniform character formula.

In chevie, it is obtained using

gap> W := CoxeterGroup("A",2);
CoxeterGroup("A",2)
gap> FakeDegrees(W,x);        
[ x^3, x+x^2, 1 ]

Trivial conflict with #25483. If my changes in dd7c992 are good, then positive review.
