Presentation

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

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

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