Presentation

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

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

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