As time permits I shall make these graphs available, along with others that I have on file. In the meantime, the two families referred to above can be obtained below as zero-one matrices.
There are four sets of parameters for strongly regular graphs on 36 vertices, two of which give rise to unique graphs. In the case of the other two, the exact numbers were not known at the time I wrote the paper
There it was found that there are at least 32,548 srg's with parameters (36,15,6,6), at least 180 with parameters (36,21,12,12) and consequently the same number of complementary graphs (36,14,4,6). Recently Brendan McKay and I completed the search for all these strongly regular graphs and found that the lower bounds mentioned here are in fact also upper bounds. This follows from the fact that we found there are precisely 227 regular two-graphs on 36 vertices. This result has been written up and now appears in the Australasian Journal of Combinatorics. For those interested I have included here a list of the 32,548 graphs with parameters (36-15-6-6) (4.5Mb) compressed using bzip2. Also, there are 3,854 descendants of the 227 regular two-graphs on 36 vertices. These are obtained by isolating a vertex by switching and then deleting it to get a strongly regular graph with parameters (35-18-9-9). These can be obtained either as a texfile of (0,1) incidence matrices, below (4.64Mb), or its compressed form (36-18-9-9.bz2) (286Kb)
In a further classification, Willem Haemers and I have determined all SRG's(64,18,2,6). The paper is entitled The Pseudo-Geometric Graphs for Generalised Quadrangles of Order (3,t), European J. Combin. 22 (2001), no. 6, 839-845, while the graphs found are all listed here.
Finally, I have succeeded in completing the search for the (45,12,3,3) strongly regular graphs. There are precisely 78 of these and I have listed them here. The final results were written up with K. Coolsaet and J. Degraer
