Presentation

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

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

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