Description (last modified by rlm)

This ticket is motivated by #10994 and #11032.

The goals will be:

  1. Remove automorphism_group_binary_code.
  1. Fix permutation_automorphism_group as noted in #10994.
  1. Use the dual code when appropriate.

Depends on #10871.

Once all of these goals are implemented we will also be able to delete almost all of binary_code.pyx, using sage/groups/perm_gps/partn_ref instead.

Applies fine to a 10.6.6 mac running 4.7.a1. Passes sage -testall. Code patches and docstrings in reference manual look good.

Thanks Robert.

Jeroen,

Could you consider merging #11033 into the sage-4.7 series? It fixes several different issues at once, and I personally consider it somewhat high priority.

Thanks, Robert

As a result of this ticket, we can now close #10994 and #11032. I'll leave this up the the release manager.
