Presentation

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

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

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