Presentation

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

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

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