Presentation

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

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

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