# How to iterate over finite fields

In my current code I have to iterate over $GF(2^7)$ four times:

```
en1 = enumerate(gf)
en2 = enumerate(gf)
en3 = enumerate(gf)
en4 = enumerate(gf)
for i,x0 in en1:
for j,x1 in en2:
for k,x2 in en3:
for m,x3 in en4:
```

In the loop I evaluate some multivariate polynomial. But this is very memory hungry. Is there any better way to do this?
