Presentation

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

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

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