Presentation

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

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

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