minimal degreeμ(G) = 51
transitive degreeμt(G) = 608

A minimal faithful permutation representation — 4 generators on 51 points:

(1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19)(20,21,24,29,25,28,39,43)(22,30,33,44,32,26,37,41)(23,34,35,45,36,27,38,42)(31,40,48,50,47,46,49,51);(20,22)(21,26)(23,31)(24,37)(25,32)(27,40)(28,30)(29,44)(33,39)(34,46)(35,49)(36,47)(38,48)(41,43)(42,51)(45,50);(26,30)(40,46)(41,44)(50,51);(20,23,25,36)(21,27,28,34)(22,31,32,47)(24,38,39,35)(26,40,30,46)(29,45,43,42)(33,49,37,48)(41,51,44,50)
