Suppose that  is a finite group. Then the set of all prime divisors of  is denoted by  and the set of element orders of  is denoted by . Suppose that . Then the number of elements of order  in  is denoted by  and the sizes of the set of elements with the same order is denoted by ; that is, . In this paper, we prove that if  is a group such that , where , then . Here  denotes the family of Suzuk...

In this paper, without using the classification of finite simple groups, we determine the structure of  finite simple groups whose Sylow 3-subgroups are of the order 9. More precisely, we classify finite simple groups whose Sylow 3-subgroups are elementary abelian of order 9.

Many fault-tolerant distributed applications can be structured as one or more groups of objects that cooperate by multicasting invocations on member objects. The building of group based applications is considerably simplified if the members of a group can multicast reliably and have a mutually consistent view of the order in which events (such as invocations, host machine failures) have taken p...
