Presentation

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

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

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