Comment:
Here it is, I called the fan Sigma rather than Delta:
'''Proposition''' The Chow group A_k_(X) of an arbitrary toric variety X =
X(Sigma) is generated by the classes of the orbit closures V(sigma) of the
cones of dimension n-k of Sigma.
So yes, the patch does implement the "honest Chow group" with the
exception that arbitrary subvarieties cannot be translated into their Chow
cycles (I think).
Karl, do you plan to review the patch completely? It is fine if no, I am
going to do it in the near future. But if yes, it certainly will be great
to have more people looking at our toric stuff ;-)
