Presentation

minimal degreeμ(G) = 29
transitive degreeμt(G) = 160

A minimal faithful permutation representation — 3 generators on 29 points:

(1,2,3,4,5)(6,7)(8,12,13,10)(9,11)(15,19,21,24)(20,28,29,27);(6,8)(7,10)(9,13)(11,12)(14,15)(16,20)(17,24)(18,21)(19,26)(22,27)(23,29)(25,28);(14,16,18,23)(15,20,21,29)(17,25,26,22)(19,27,24,28)
