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