Presentation

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

A minimal faithful permutation representation — 5 generators on 24 points:

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