Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 128

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

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