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