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