Comment (by stumpc5):
What about
{{{
sage: S = SimplicialComplex(vertex_set=[1,2,3,4],maximal_faces=[[1,4],
[2,4]])
/home/stumpc5/progs/sage-5.5.beta1/local/bin/sage-ipython:1:
DeprecationWarning: vertex_set is deprecated.
See http://trac.sagemath.org/12587 for details.
#!/usr/bin/env python
sage: S
Simplicial complex with vertex set (1, 2, 3, 4) and facets {(2, 4), (1,
4)}
}}}
sorry to be picky here: I thought we agreed that the input
{{{vertex_set}}} is ignored, didn't we ? Mathematically, the above is
simply wrong (see comment:22), so I would prefer if we could get rid of
{{{
Simplicial complex with vertex set (1, 2, 3, 4) and facets {(2, 4), (1,
4)}
}}}
Or do you think that deprecation enough?
