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