Presentation

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

A minimal faithful permutation representation — 3 generators on 24 points:

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