Comment(by kcrisman):
Just a minor point - there is a lot of reference to the Chow group of this
and that, but it's apparently only the 'toric' Chow group, as noted at the
beginning of the file. Is it typical in the literature to conflate these
notions - or is there a theorem that they are equivalent for toric
varieties? This should be clarified somehow, maybe even with an example
of where they are not the same. It would be unfortunate if they were
*not* the same and someone later wanted to implement regular Chow groups!
Forgive me if the question is naive; I am fairly familiar with 'regular'
Chow groups but hadn't encountered this (natural) version before. If
there is a foundational paper, it would be helpful to refer to that in the
documentation as well; the Wikipedia page referenced doesn't actually
refer to the 'toric' variety at all.
