Presentation

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

A minimal faithful permutation representation — 3 generators on 24 points:

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