ambiguous. I would say "two distinct elements" if that's definitely what we mean. (I think it's a slightly controversial point whether there's a one-element
Boolean algebra; in my usage there is not, but I'm not sure there's a complete consensus on it in the literature.)
358:
I think it is typical (See for instance page 10 of "Introduction to
Boolean algebras" by Paul Halmos) that in the definition of the algebra, $ 0$ and $ 1$ are distinct elements. Should I make the change?

Does this have a standard name? It follows immediately from distributivity, of course. Should it be mentioned in the article? --
