minimal degreeμ(G) = 36
transitive degreeμt(G) = 64

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

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