Presentation

minimal degreeμ(G) = 37
transitive degreeμt(G) = 160

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

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