Presentation

minimal degree	μ(G) = 24
transitive degree	μ_t(G) = 128

A minimal faithful permutation representation — 5 generators on 24 points:

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