Presentation

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

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

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