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