Presentation

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

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

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