Presentation

minimal degreeμ(G) = 31
transitive degreeμt(G) = 448

A minimal faithful permutation representation — 3 generators on 31 points:

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