Presentation

minimal degree	μ(G) = 24
transitive degree	μ_t(G) = 64

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

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