Comment (by mabshoff):
Yes, there is some slight, easy to fix, doctest failure:
{{{
sage -t -long devel/sage/sage/graphs/graph.py
**********************************************************************
File "/scratch/mabshoff/release-cycle/sage-3.1.3.alpha0/tmp/graph.py",
line 6234:
sage: for g in L:
G = g.automorphism_group()
G.order(), G.gens()
Expected:
(24, ((2,3), (1,2), (1,4)))
(4, ((2,3), (1,4)))
(2, ((1,2),))
(8, ((1,2), (1,4)(2,3)))
(6, ((1,2), (1,4)))
(6, ((2,3), (1,2)))
(2, ((1,4)(2,3),))
(2, ((1,2),))
(8, ((2,3), (1,4), (1,3)(2,4)))
(4, ((2,3), (1,4)))
(24, ((2,3), (1,2), (1,4)))
Got:
(24, [(2,3), (1,2), (1,4)])
(4, [(2,3), (1,4)])
(2, [(1,2)])
(8, [(1,2), (1,4)(2,3)])
(6, [(1,2), (1,4)])
(6, [(2,3), (1,2)])
(2, [(1,4)(2,3)])
(2, [(1,2)])
(8, [(2,3), (1,4), (1,3)(2,4)])
(4, [(2,3), (1,4)])
(24, [(2,3), (1,2), (1,4)])
