Presentation

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

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

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