Hi Robert and William!
Thanks for your pointers!
devel/sage/sage/graphs seems to be solely dealing with undirected graphs.
What I would really like to have is isomorphisms between colored directed graphs
such as
sage: T = CrystalOfTableaux(['A',2],shape=[2])
sage: T.plot()
or
sage: view(T, pdflatex = True)
More precisely, I would like the explicit isomorphism between the following two
colored directed graphs:
sage: B1 = CrystalOfTableaux(['A',2],shape=[1])
sage: B2 = CrystalOfTableaux(['A',2],shape=[2])
sage: T = TensorProductOfCrystals(B1,B2,
generators=[[B1.module_generators[0],B2.module_generators[0]]])
sage: TT = TensorProductOfCrystals(B2,B1,
generators=[[B2.module_generators[0],B1.module_generators[0]]])
sage: view(T, pdflatex = True)
sage: view(TT, pdflatex = True)
or
sage: T.plot()
sage: TT.plot()
if the above does not work. Well and then later between graphs that do not have
unique sinks anymore.
Is this already possible?
Thanks,
Anne

William, could you give me a point to Robert Miller's "NICE" package. Where

I find information about it?
Please feel free to email me directly with questions!
It's what is used when you call commands like "is_isomorphic",
"canonical_label", "automorphism_group", etc., on any Sage graph.
It's just included in Sage. It's in Cython code in
devel/sage/sage/graphs/.
No it's not. It used to be there, but now it also handles linear
codes, matrices, etc. It is located in sage/groups/perm_gps/partn_ref.
