초록

In this paper, we characterize some PGL(2, q) by their orders and maximum element orders. We also prove that PSL(2, p) with p ≥ 3 a prime can be determined by their orders and maximum element orders. Moreover, we show that, in general, if q = pn with p a prime and n > 1, PGL(2, q) can not be uniquely determined by their orders and maximum element orders. Several known results are generalized.

Abstract

In this paper, we characterize some PGL(2, q) by their orders and maximum element orders. We also prove that PSL(2, p) with p ≥ 3 a prime can be determined by their orders and maximum element orders. Moreover, we show that, in general, if q = pn with p a prime and n > 1, PGL(2, q) can not be uniquely determined by their orders and maximum element orders. Several known results are generalized.
