Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 256

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

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