Presentation

minimal degree	μ(G) = 24
transitive degree	μ_t(G) = 512

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

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