Presentation

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

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

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