Presentation

minimal degreeμ(G) = 29
transitive degreeμt(G) = 1280

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

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