In labelled automorphism group test, why not have d = digraphs.DeBruijn(3,2)
at the very beginning?
In the check for correct domain in the empty group case, is there any reason for changing the output from a set to a sorted list?

Replying to kdilks:

Right, done.
In the check for correct domain in the empty group case, is there any reason for changing the output from a set to a sorted list?
In py2 we always get {'a', 'b'}
, but in py3 I get {'b', 'a'}
. So I proposed to used a sorted list to ensure that we always get the same result. Alternatives are to tag doctests as # py2
or # py3
, or to change the test to check equality with the set {'a', 'b'}
, etc. I don't know which is the best option here.

Why not make it Graph({'a':['a'], 'b':[]}).automorphism_group().domain() == {'a', 'b'}
returns True
?

comment:7 Changed 10 months ago by
Agreed. It better shows that the output is a set. Thanks.
comment:8 Changed 10 months ago by
It looks like the test doesn't work this way, presumably because ag.domain()
is <class 'sage.sets.finite_enumerated_set.FiniteEnumeratedSet_with_category'>
, and {'a', 'b'}
is just <type 'set'>
.
comment:9 Changed 10 months ago by
sage: from sage.sets.finite_enumerated_set import FiniteEnumeratedSet sage: F = FiniteEnumeratedSet(['a', 'b']) sage: F {'a', 'b'} sage: type(F) <class 'sage.sets.finite_enumerated_set.FiniteEnumeratedSet_with_category'> sage: ag = Graph({'a':['a'], 'b':[]}).automorphism_group() sage: ag.domain() {'b', 'a'} sage: type(ag.domain()) <class 'sage.sets.finite_enumerated_set.FiniteEnumeratedSet_with_category'> sage: ag.domain() == F False
So I propose to return to my previous proposal unless you have a better solution.
comment:10 Changed 10 months ago by
I'm fine with the previous proposal. It looks like domain()
really needs to be a FiniteEnumeratedSet?() to play nicely with GAP.

So let's go back to something that is working. Thanks.
comment:13 Changed 10 months ago by
I just tried over 8.7.beta5 and it's working well. So can we set this ticket to positive review ?
comment:14 Changed 10 months ago by
Trying to get my computer updated to 8.7b5 so I can doublecheck.
