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