Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 256

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

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