Presentation

minimal degreeμ(G) = 39
transitive degreeμt(G) = 896

A minimal faithful permutation representation — 4 generators on 39 points:

(1,2,3,4,5,6,7)(8,9,13,16,14,10,12,18)(11,17,20,23,21,15,19,22)(24,25,29,32,28,31,37,39)(26,33,35,36,34,30,38,27);(8,10,14,9)(11,17,21,15)(12,16,13,18)(19,22,20,23)(24,26)(25,30)(27,32)(28,34)(29,35)(31,33)(36,39)(37,38);(8,11,13,20,14,21,12,19)(9,15,16,22,10,17,18,23)(24,27,29,33,28,36,37,30)(25,26,32,35,31,34,39,38);(9,10)(15,17)(16,18)(22,23)(26,34)(27,36)(30,33)(35,38)
