Presentation

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

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

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