Presentation

minimal degreeμ(G) = 31
transitive degreeμt(G) = 896

A minimal faithful permutation representation — 4 generators on 31 points:

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