Regarding
{{{
sage -t -long -force_lib "devel/sage-
main/sage/combinat/words/nfactor_enumerable_word.py"
**********************************************************************
File "/usr/share/sage/devel/sage-
main/sage/combinat/words/nfactor_enumerable_word.py", line 20:
sage: it.next()
Expected:
word: 6456
Got:
word: 5645

With python-2.7
{{{
sage: w = Word([4,5,6])^7
sage: w
word: 456456456456456456456
sage: it = w.factor_iterator(4)
sage: it.next()
word: 5645
sage: it.next()
word: 6456
sage: it.next()
word: 4564
}}}
with python-2.6
{{{
sage: w = Word([4,5,6])^7
sage: w
word: 456456456456456456456
sage: it = w.factor_iterator(4)
sage: it.next()
word: 6456
sage: it.next()
word: 5645
sage: it.next()
word: 4564
}}}
So it looks like with python 2.6 we where moving in the series of number
with a stride 2 while python 2.7 works through the sequence with a stride
1.
