SUMMARY

The discussion centers on proving that if ## p \geq q \geq 5 ## and both ## p ## and ## q ## are prime numbers, then ## 24 \mid p^2 - q^2 ##. The proof utilizes modular arithmetic to establish that both ## p^2 - q^2 ## is divisible by 3 and 8. The factorization of the difference of squares, ## p^2 - q^2 = (p - q)(p + q) ##, is crucial in demonstrating the divisibility by 24. The participants emphasize the importance of recognizing patterns in prime numbers and the necessity of clear factorization techniques.

That's far too long. You only need ##p = q + 2k##. You don't need the rest of those variables. To do something rigorously you don't need to write out every detail.

You seem so focused on the details that you forget the ideas involved and what is important.
