Presentation

minimal degreeμ(G) = 51
transitive degreeμt(G) = 2432

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