Presentation

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

A minimal faithful permutation representation — 3 generators on 24 points:

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