Presentation

minimal degreeμ(G) = 37
transitive degreeμt(G) = 160

A minimal faithful permutation representation — 4 generators on 37 points:

(1,2,3,4,5)(6,7,11,16,12,15,10,26)(8,17,19,13,21,29,20,28)(9,22,24,14,25,31,23,30)(18,33,34,32,35,27,36,37);(6,8,11,19,12,21,10,20)(7,13,16,29,15,28,26,17)(9,18,24,34,25,35,23,36)(14,27,31,37,30,33,22,32);(6,9)(7,14)(8,18)(10,23)(11,24)(12,25)(13,27)(15,30)(16,31)(17,32)(19,34)(20,36)(21,35)(22,26)(28,33)(29,37);(7,15)(13,28)(14,30)(16,26)(17,29)(22,31)(27,33)(32,37)
