Comment (by vdelecroix):
Hi,
The documentation is indeed much better!
And I would put the following inside `EXAMPLES` and not `TESTS`
{{{
sage: perm4 = polytopes.permutahedron(4)
sage: perm4.graph().is_isomorphic(graphs.BubbleSortGraph(4))
True
}}}
It is nice to show how to play with these. Usually, I put in `TESTS` only
things that are of no interest like
{{{
sage: for i in range(n):
....: M = MyObject(i)
....: assert M.one_way() = M.other_way()
}}}
or checking ouptut type, or testing some crazy input arguments.
This is too much repetitions for me
{{{
In total, `B(n)` has order `n!`. Thus, the order
of `B(n)` increases according to `f(n) = n!`.
}}}
Vincent
