Presentation

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

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

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