Presentation

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

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

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