Presentation

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

A minimal faithful permutation representation — 5 generators on 24 points:

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