Presentation

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

A minimal faithful permutation representation — 3 generators on 24 points:

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