R1, (r0, r1, s1, s2) = QQ['r0', 'r1', 's1', 's2'].objgens()
R2, z = R1['z'].objgen()
R3, zb = R2.quo(z**3 + r1*z + r0, names='zb').objgen()

s = s1*z + s2*z**2

f1 = R3(s*1)
f2 = R3(s*z)
f3 = R3(s*z**2)
print vector(f1)

Spins off into 100% CPU land.

Component: basic arithmetic

Keywords: polynomial rings vector
