Presentation

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

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

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