Presentation

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

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

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