Presentation

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

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

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