Presentation

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

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

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