Which of the following statements are true?

- If \(n\) is a prime number and a square number, then \(n\) is a triangular number.
- If \(n\) is a prime number and a square number, then \(n\) is not a triangular number.

Assumption:

Assume classical logic, in particular the law of excluded middle: \(p \vee \neg p\) is a tautology.

Notes:

- A prime number is a positive integer greater than \(1\) that is only divisible by \(1\) and itself.
- A square number is an integer that can be expressed in the form \(n^2\) for some integer \(n\).
- A triangular number is an integer that can be expressed in the form \(\frac{n(n+1)}{2}\) for some integer \(n\).
