Presentation

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

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

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