Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 32

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

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