Presentation

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

A minimal faithful permutation representation — 5 generators on 24 points:

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