Presentation

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

A minimal faithful permutation representation — 4 generators on 29 points:

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