Presentation

minimal degreeμ(G) = 51
transitive degreeμt(G) = 1216

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