Description

We pull many things from Chevie that are hard-coded. We should rather hardcode those ourselves, plus other stuff that is either hard to compute, or easy to hard-code.

We currently think of hard-coding:

  • degrees/codegrees
  • fake degree polynomials
  • fundamental invariants
  • roots, coroots, fundamental weights
  • representatives of conjugacy classes
  • field of definition
  • cartan matrix
  • tba

At Days93.51, we have been porting all hard-coded data files from chevie to python (untested and probably containing tons of errors still), these can be found at

https://github.com/jmichel7/gap3-jm/tree/master/sage/cheviedata

and will be updated when we find issues.
