Presentation

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

A minimal faithful permutation representation — 3 generators on 24 points:

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