### division_polynomial with integer coefficients?!

Hi, I would like to get a Division-polynomial for an elliptic curve. The curve is

```
E=EllipticCurve(CC,[-35/4,-49/4])
```

I used the commands

```
E3 = E.change_ring(QQbar)
p = E3.division_polynomial(3, two_torsion_multiplicity=0)
```

and I obtained

```
3*x^4 - 105/2*x^2 - 147*x - 1225/16
```

Is there a way to get a division-polynomial which has integer coefficients and which is normalized?
