Presentation

minimal degreeμ(G) = 29
transitive degreeμt(G) = 320

A minimal faithful permutation representation — 4 generators on 29 points:

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