Presentation

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

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

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