Presentation

minimal degreeμ(G) = 27
transitive degreeμt(G) = 162

A minimal faithful permutation representation — 3 generators on 27 points:

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

Polycyclic presentation:
