Presentation

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

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

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