Presentation

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

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

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