Presentation

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

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

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