Presentation

minimal degreeμ(G) = 35
transitive degreeμt(G) = 1792

A minimal faithful permutation representation — 3 generators on 35 points:

(1,2,3,4,5,6,7)(8,9,11,10)(13,16)(14,18)(17,19)(20,21,26,31)(22,32,23,34)(24,30,25,29)(27,35,28,33);(8,10,11,9)(14,18)(16,19)(20,22,26,23)(21,27,31,28)(24,35,25,33)(29,34,30,32);(12,13)(14,19)(15,17)(16,18)(20,23,26,22)(21,28,31,27)(24,35,25,33)(29,34,30,32)
