Presentation

minimal degreeμ(G) = 29
transitive degreeμt(G) = 288

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

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