#4341: [with patch, needs review] Optimisations + corrections to latin.py
-----------------------------+----------------------------------------------
Reporter: carlohamalainen | Owner: mhansen
Type: enhancement | Status: new
Priority: minor | Milestone: sage-3.2
Component: combinatorics | Keywords:
-----------------------------+----------------------------------------------
* Removed code that used gap.Representative in an unsafe manner (assumed
that the ordering would be the same on each execution but the GAP manual
says that this may not be the case). Previous code did work but was not
safe.
* Replacement tau_to_bitrade uses correct and straightforward
combinatorial approach.
* Replacement of p3_group_bitrade_generators is orders of magnitude
faster; uses GAP's IsomorphismPermGroup instead of explicitly constructing
a natural homomorphism.
