%N Number of finite noncyclic simple groups whose maximal order prime divisor is the n-th prime

%H A. V. Zavarnitsine, <a href="http://arxiv.org/abs/0810.0568v1">Finite simple groups with narrow prime spectrum</a> arXiv:081.0568 and Sib. Elec. Math. Rep. 6 (2009) 1-12

%e a(17)=3 because there are precisely three non-Abelian finite simple groups G (viz. PSL(2,59), A_59, A_60) such that the maximal prime divisor of the order of G is the 17th prime (which is 59).

%Y Cf. A001034

%K nonn

%O 1,3
