Presentation

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

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

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