Why do you use = is the last 3 lines?

I can't reproduce this problem. The following works for me:
\begin{axiom}
)clear completely
(a0,a1,a2,a3):Polynomial Integer
(a00,a01,a02):Polynomial Integer
A0:=vector [a00,a01,a02]
(a10,a11,a12):Polynomial Integer
A1:=vector [a10,a11,a12]
X:=cross(A0,A1)
(a20,a21,a22):Polynomial Integer
A2:=vector [a20,a21,a22]
(a30,a31,a32):Polynomial Integer
A3:=vector [a30,a31,a32]
Y:=cross(A2,A3)
B0 := A0 + a0*X + a0*Y
B1 := A1 + a1*X + a1*Y
B2 := A2 + a2*X + a2*Y
B3 := A3 + a3*X + a3*Y
C0 := cross(B0,B1)
C1 := cross(B2,B3)
D := cross(C0,C1);
\end{axiom}

But the last expression if vary large and is too large
to display on here on MathAction.

Please post the actual Axiom commands that will cause
Axiom to hang.
