Presentation

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

A minimal faithful permutation representation — 3 generators on 37 points:

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