Presentation

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

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

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