Presentation

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

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

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