Presentation

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

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

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