Presentation

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

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

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