Presentation

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

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

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