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