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