Presentation

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

A minimal faithful permutation representation — 5 generators on 24 points:

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