Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 128

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

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