Presentation

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

A minimal faithful permutation representation — 4 generators on 24 points:

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