Presentation

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

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

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