Presentation

minimal degree	μ(G) = 24
transitive degree	μ_t(G) = 64

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

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