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