Regular Two-graphs on 36 vertices
The recent CRC Handbook of Combinatorial Designs (C.J. Colbourne
and J.H. Dinitz, eds) contains a Chapter by the author on "Two-Graphs".
To save space in that volume, which is already huge (and well-worth
you persuading your library to purchase!) tables of Two-graphs were
omitted. Should you wish further information on these tables, follow
