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