A characterization of symplectic groups related to Fermat primes

Comment.Math.Univ.Carolin. 62,1 (2021) 33-40.

Abstract: We proved that the symplectic groups \mathrm{PSp}(4,2^{n}), where 2^{2n}+1 is a Fermat prime number is uniquely determined by its order, the first largest element orders and the second largest element orders.

Keywords: element order; the largest element order; prime graph; symplectic group
