On (2, 3, t)-Generations for the Rudvalis Group Ru


A group G is said to be(2,3,t) -generated if it can be generated by an involution x and an element y so that 0(y)=3 and 0(xy)=t. In the present article, we determine all (2,3,t)-generations for the Rudvalis sporadic simple group Ru, where t is any divisor of .
