Presentation

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

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

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