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