Presentation

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

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

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