Presentation

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

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

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

Polycyclic presentation:

2^8|a^2=f,d^2=g,e^2=g,f^2=h,b^a=be,c^a=ch,d^a=dg,e^a=eg,e^b=eg
