Presentation

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

A minimal faithful permutation representation — 4 generators on 35 points:

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