minimal degreeμ(G) = 40
transitive degreeμt(G) = 966

A minimal faithful permutation representation — 2 generators on 40 points:

(1,2,4,6,8,10,12,14,16,18,20,22,23,21,19,17,15,13,11,9,7,5,3)(25,26)(27,28)(29,30)(31,32)(35,36)(37,38)(39,40);(2,3)(4,5)(6,7)(8,9)(10,11)(12,13)(14,15)(16,17)(18,19)(20,21)(22,23)(24,25,26)(28,29)(30,31)(32,33)(34,35,37,39,40,38,36)
