Comment (by dimpase):
I just checked this out, and the definition is not right.
With such a definition e.g. every vertex-transitive graph is
distance-regular, and this is clearly nonsense! I wish I had time to look
at this 6 months ago :-(
Cf. http://permalink.gmane.org/gmane.comp.mathematics.sage.support/33339
where this was pointed out...
