Presentation

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)(20,21,24,29,25,28,37,43)(22,30,33,44,32,26,36,39)(23,27,34,42,35,41,48,51)(31,38,46,49,45,40,47,50);(20,22)(21,26)(23,31)(24,36)(25,32)(27,40)(28,30)(29,44)(33,37)(34,47)(35,45)(38,41)(39,43)(42,49)(46,48)(50,51);(20,23,25,35)(21,27,28,41)(22,31,32,45)(24,34,37,48)(26,38,30,40)(29,42,43,51)(33,46,36,47)(39,49,44,50);(21,28)(24,37)(26,30)(27,41)(33,36)(34,48)(38,40)(46,47)
