Which Italian abbreviation is correct Nº, No. or n.
Which abbreviation for the number in Italian is correct: Nº, No., n., ...
I think that Nº is the right one, but on the other hand I can see that Italians use Nº and n. at the same time. I don't understand why. It shouldn't be allowed both forms?

Can be written "Nº" also in the middle of the sentence or it even must be written so.
