Presentation

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

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

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