comment Looking for deterministic criteria to generate the symmetric group?
Dear Marty, I just read the proof of your theorem which looks good. I'm confused though about one point. The group $S_n$ admits a subgroup of index $2$ namely $A_n$. It is true though that if $e:=[S_n:H]>2$ then $e≥n$. Moreover, it is true that $A_n$ has the property which you used in your proof namely that if $e:=[A_n:H]>1$ then $e≥n$.

Thanks a lot Marty for pointing out the mistake in my "original proof".

comment Looking for deterministic criteria to generate the symmetric group?
@Marty comment below is true. There is a gap in the proof above. Implicitely implied in the proof above was the belief that the semi-direct product $S_{2}^{n}\rtimes S_n$ had no cycle of length $>n$. This is (in retrospect) clearly false.

Hi Atsushi, may I find this relation in Klingen's book on Siegel modular forms?

Dear Kanazawa, do you have a reference for the asymptotic identity given above. I would be quite interested to see how you proved it.
