Presentation

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

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

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