Presentation

minimal degreeμ(G) = 29
transitive degreeμt(G) = 320

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

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