Partial backport of my work branch to master

  • Performance improvement to automorphism group/group isomorphism *
  • Clean away the messy EFactors function in DataAboutSimpleGroup
  • Store Solvability of extensions, if known
  • Have RankAction test transitivity (was requested)
  • FIX: Improvements in how MTC deletes superfluous generators -- avoid error message in ghomomorphisms for FpGroups. *
  • Performance improvement in IntermediateSubgroups if the smaller subgroup has many orbits *

(The ones with * merit mentioning in the release notes)

@hulpke hulpke added kind: enhancement Label for issues suggesting enhancements; and for pull requests implementing enhancements kind: bug: unexpected error Issues describing bugs in which computation unexpectedly encounters an error, and PRs fixing them release notes: to be added PRs introducing changes that should be (but have not yet been) mentioned in the release notes kind: performance labels Apr 16, 2021
@hulpke hulpke added this to the GAP 4.12.0 milestone Apr 16, 2021

Thanks @hulpke. I don’t have time to review at the moment, but I’ll note that GitHub renders - and * as the same bullet point icon, so it’s not obvious which ones you mean for release notes. (Update: I added a * to the end of these items 🙂)

Thank you @wilfwilson (and I was so proud of using two different bullets... :-( )
