Presentation

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

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

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