Presentation

minimal degree	μ(G) = 24
transitive degree	μ_t(G) = 64

A minimal faithful permutation representation — 3 generators on 24 points:

(1,2,4,7,5,8,3,6)(9,10,12,18,13,20,11,21,14,19,22,15,24,16,23,17);(10,15,19,18)(11,22)(12,23)(13,24)(16,17,20,21);(1,3,5,4)(2,6,8,7)(10,16,19,20)(11,23)(12,22)(15,17,18,21)
