Presentation

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

A minimal faithful permutation representation — 3 generators on 24 points:

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