Presentation

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

A minimal faithful permutation representation — 3 generators on 36 points:

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