Presentation

minimal degreeμ(G) = 16
transitive degreeμt(G) = 64

A minimal faithful permutation representation — 4 generators on 16 points:

(1,2,3,4)(10,11)(14,15);(6,8)(9,10,13,11)(12,15,16,14);(1,2)(3,4)(5,6)(7,8)(9,11,13,10)(12,15,16,14);(1,2)(3,4)(9,12)(10,14)(11,15)(13,16)

Polycyclic presentation:
