Presentation

minimal degreeμ(G) = 34
transitive degreeμt(G) = 128

A minimal faithful permutation representation — 4 generators on 34 points:

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