Presentation

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

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

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