[sage-support] Generation of graphs where all maximal cliques have the same size

2017-10-19 Thread Christian Stump
Hi, how can I generate, in a fast enough way, connected graphs for which the clique complex is pure, ie, for which all containmentwise maximal cliques are of the same size ? Fast enough here means that I can produce examples of such graphs with 20 vertices, edge degrees between 10 and 14 (an
