Presentation

minimal degreeμ(G) = 29
transitive degreeμt(G) = 640

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

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