Reporter: vdelecroix | Owner: vdelecroix
Type: defect | Status: needs_work
Priority: major | Milestone: sage-5.11
Component: combinatorics | Resolution:
Keywords: iet, combinatorics | Work issues:

Changes (by jdemeyer):
* status: positive_review => needs_work
* dependencies: #12643, #13677 => #12643, #13677, #14669
Old description:
> 1) The library for iet is moved from sage.combinat.iet to
> sage.dynamics.interval_exchanges which seems more natural.
>
> We postpone 2) and 3) below to #14683
>
> 2) The old version for iet uses two kinds of datatype for reduced and
> labeled versions. The new implementation makes them coherent.
>
> 3) As a by product of 2), the following behavior is corrected
> {{{
> sage: p = iet.Permutation('a b','b a')
> sage: q = iet.Permutation('b a','a b')
> sage: p == q
> True
> }}}
>
> Apply
> * [attachment:trac_8386_really_just_moving-fc.patch]
> * [attachment:trac_8386_big_clean_fc.patch]
