Presentation

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

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

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