Presentation

minimal degreeμ(G) = 36
transitive degreeμt(G) = 128

A minimal faithful permutation representation — 2 generators on 36 points:

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