Presentation

minimal degree	μ(G) = 24
transitive degree	μ_t(G) = 128

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

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