What is a strictly positive integer? Can we change the wording to: "Let n be a positive integer and let E_n be the set of n-tuples of positive integers."

What a strictly positive integer is can be found on the web.
Google for: strictly positive or strictly positive integer.

Saying only "positive" rather than "strictly positive" may introduce ambiguity (for some) since some may consider 0 to be a positive integer. Rather than assert these people are all definitely wrong, I think it's better to use an extra word to make sure it's absolutely clear what they mean here.
