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