Presentation

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

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

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