# Upper bound on the number of vertex-transitive graphs

Is there a known upper bound on the number of vertex transitive graphs on $n$ vertices?

• Since vertex transitive graphs are regular, you can get some trivial bounds, but I guess they are not tight. Have you considered this? – Vinicius dos Santos Jan 23 '14 at 2:06
• Question was asked on MathOverflow as well, see here. – Gregor Jan 28 '14 at 20:16
• The question has an accepted answer at MO: mathoverflow.net/a/155446 – András Salamon Mar 11 '14 at 21:41
