Presentation

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

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

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