Presentation

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

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

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