Presentation

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

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

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