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