Presentation

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

A minimal faithful permutation representation — 5 generators on 24 points:

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