A "Pythagorean Plus One" triple is not defined as being a pythagorean triple.  It may seem to imply that it is a pythagorean triple by the name, but it doesn't, that's just what Gamer chose to name it.

As for a triple that is both a "pythagorean plus one" triple and a pythagorean triple, I think it is impossible.

Notice that in the above line, there is no positive real solution for both a and b.

Edit: Fixed sqrt sign and sqr signs
