Hi all,
Sometimes, especially with functions of 8 variables, the
BooleanFunction.truth_table() method with format='hex" gives wrong values
that are the wrong length.
I don't yet have a login to Trac. Should I obtain one and report the bug
there?
All the best, Paul

Hi,
I have attached the output file here. I am sorry that I have not put more
time into cleaning up the code and the output.
Once you figure out what the output is trying to tell you, you will see
that the relevant pairs of strongly regular graphs are isomorphic for dim=4
and dim=6, and also

Thanks, Dima.
The strongly regular graph parameters are always the same. The graphs
themselves are in some cases not isomorphic. In my next message I will post the
relevant output from my code.

Since asking the question "How should I determine if two strongly regular
graphs are isomorphic?" I have made great progress in classifying Bent
functions by their Cayley graphs.
That is, up until now. I have found two graphs which I was (emprically)
expecting to be isomorphic have different

I am currently trying to use Sage to classify bent functions by their
Cayley graphs.
I have attached an example where I have two (256, 120, 56, 56) strongly

not equal h, and so g and h are not isomorphic.

Hi,
I am seeing a problem where "g.is_isomorphic(h)" is taking an inordinately

"g.canonical_label() == h.canonical_label()" both take a reasonable time.

DETAILS:
I downloaded sage-7.2.tar.gz to my home Linux box:
I also could not reproduce the problem with the worksheet you gave me. I
