Comment(by SimonKing):
I forgot to mention:
{{{
Tower of polynomial rings over a number field
sage: Q.<t> = QQ[]
sage: K.<tau> = NumberField(t^2+t+1)
sage: P.<x,y> = K[]
sage: R.<z> = P[]
sage: p = tau + tau^2*x*z + tau^3*y*z^2 + (1+tau)*x*y*z
sage: gap(p)
y*z^2+((tau+1)*x*y+(-tau-1)*x)*z+tau
}}}
works as well!
