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