Presentation

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

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

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