Presentation

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

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

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