Presentation

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

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

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