Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 128

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

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