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