Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 64

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

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