Presentation

minimal degree	μ(G) = 24
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 6 generators on 24 points:

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