Presentation

minimal degreeμ(G) = 29
transitive degreeμt(G) = 320

A minimal faithful permutation representation — 3 generators on 29 points:

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