Presentation

minimal degreeμ(G) = 35
transitive degreeμt(G) = 768

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

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