Presentation

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

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

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