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