Presentation

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

A minimal faithful permutation representation — 2 generators on 37 points:

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