Presentation

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

A minimal faithful permutation representation — 4 generators on 24 points:

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