Presentation

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

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

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