Presentation

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

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

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