# Enumerating points in 0-dimensional ideals over Qbar

I would like to find the points of a 0-dimensional ideal over Qbar. That is I do not want just the rational points,

The problem is that I found multiple problem while doing that.

1) While the code

```
R.<t1,t2,t3,e1,e2,e3> = PolynomialRing(QQbar,6, order="degrevlex(3),lex(3)")
```

is legal, the code

```
R.<t1,t2,t3> = PolynomialRing(QQbar,6, order="degrevlex(3)")
```

is not for reasons that esapes me.

2) The code

```
R.<t1,t2,t3,e1,e2,e3> = PolynomialRing(QQbar,6, order="degrevlex(3),lex(3)")
tvars = [t1,t2,t3]
eltsyms = [R((SymmetricFunctions(QQbar).elementary())[i].expand(3,alphabet=tvars)) for i in range(4)]
```

is not legal, it is if we replace QQbar by QQ. Why?
