Presentation

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

A minimal faithful permutation representation — 7 generators on 24 points:

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