Presentation

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

A minimal faithful permutation representation — 3 generators on 24 points:

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