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

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

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