Presentation

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

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

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