Presentation

minimal degreeμ(G) = 34
transitive degreeμt(G) = 256

A minimal faithful permutation representation — 5 generators on 34 points:

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