Presentation

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

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

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