Dear Jos� Maria,
In Italian we have both Sommatoria (upper-case sigma) and Produttoria
(upper-case GreeK pi). Today, thanks to Nick, I have learnt that the latter
is running product in English.
Many thanks for having helped me out to solve this matter.
Ciao (this one should cross the international boundaries!),
Carlo

In Portuguese, we have somat�rio, same as soma (sum), but we do not have
produt�rio.
