Presentation

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

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

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