Presentation

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

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

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