2-arc-transitive tetravalent graphs
This collection contains a list of connected 2-arc-transitive tetravalent graphs on up to 2000 vertices. The list is complete on up to 727 vertices but misses some 7-arc-transitive graphs that admit no s-arc-transitive group for s less than 7 on more than 727 vertices, and also some 4-arc-transitive graphs that admit no s-arc-transitive group for s less than 4 on more than 1157 vertices. The list was prepared by Primož Potočnik (source).
