minimal degreeμ(G) = 43
transitive degreeμt(G) = 1216

A minimal faithful permutation representation — 4 generators on 43 points:

(1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19)(20,21,24,26)(22,25,23,27)(28,29,34,38)(30,40,36,42)(31,41,32,35)(33,39,43,37);(20,22,24,23)(21,25,26,27)(28,30)(29,32)(31,38)(33,35)(34,36)(37,42)(39,40)(41,43);(20,23,24,22)(21,25,26,27)(28,31,34,32)(29,35,38,41)(30,39,36,37)(33,42,43,40);(28,32,34,31)(29,36,38,30)(33,42,43,40)(35,37,41,39)
