Presentation

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

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

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