Presentation

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

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

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