Presentation

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

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

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