Presentation

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

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

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