Presentation

minimal degree	μ(G) = 16
transitive degree	μ_t(G) = 32

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

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

Polycyclic presentation:

2^10|a^2=g,b^2=e,e^2=j,f^2=i,b^a=bf,c^a=cg,d^b=dh,e^d=ej,f^b=fi,f^c=fi,g^b=gi,h^b=hj
