Presentation

minimal degreeμ(G) = 16
transitive degreeμt(G) = 32

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

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

Polycyclic presentation:

2^8|a^2=g,d^2=e,g^2=h,b^a=be,c^a=cf,f^a=fh,g^c=gh
