Presentation

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

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

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