Hello all,

I have a few conjectures that I want to test concerning distance-regular graphs. They would be easy to test on a computer, but I am wondering whether anyone knows of a place where I can get a ton of sample intersection arrays, in some sort of computer format, to test? For example, in the book by Brouwer, Cohen, and Neumaier has a ton of them in the back, but entering them all would take forever. I'm wondering whether someone has already done it, and would mind sharing with me.

Perahps test your conjectures on the known classes of distance-regular graphs? They are listed at mathworld.wolfram.com/Distance-RegularGraph.html . –  Joseph O'Rourke Apr 21 '11 at 11:59

See http://www.win.tue.nl/~aeb/ (the web page of A. Brouwer) -- he has data, and I am guessing that he would be receptive to questions, as well.

Thanks, that sounds like good advice. –  Greg Markowsky Apr 22 '11 at 5:47
