Presentation

minimal degreeμ(G) = 37
transitive degreeμt(G) = 320

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

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