I need all 15 ( I believe) of the Paulus graphs with 25 vertices and the other 10 with 26 vertices to be generated. I know how to generate one of each that is in the database however, I need to generate the others to test my algorithm. I just need a nudge in the right direction. Thank you.Fri, 08 Apr 2016 01:57:33 +0200https://ask.sagemath.org/question/33040/generating-graph-families-in-sage/Comment by kcrisman for <p>I am trying to figure out how to generate strongly regular graphs with parameter (25,12,5,6).

https://ask.sagemath.org/question/33040/generating-graph-families-in-sage/?comment=33081#post-id-33081Can you add a few more details for those of us not familiar with Paulus graphs? There are isomorphism class generators in Sage (e.g. `Graphs(3)`) but I don't know how well they would work with such large numbers of vertices.Tue, 12 Apr 2016 16:31:05 +0200https://ask.sagemath.org/question/33040/generating-graph-families-in-sage/?comment=33081#post-id-33081
