Presentation

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

A minimal faithful permutation representation — 6 generators on 34 points:

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