Presentation

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

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

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