ƧƿѦςɛ♏ѦਹѤʞ<a href="https://mas.to/@thepdog" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@thepdog</a> P is a prime number greater than 3. P^2 – 1 = (p – 1)(p + 1). Since 3 must divide one of any three consecutive numbers, 3 must divide (p – 1), p or (p + 1). It can’t divide p, so it must divide either (p – 1) or (p + 1). But p = 2k + 1 for some k. Hence (p – 1)(p + 1) = (2k)(2k + 2) = 4k(k + 1). Therefore 4 divides p^2 – 1. So, either k or k + 1 must itself be divisible by 2, meaning 8 divides p^2 – 1. As 8 and 3 are relatively prime, 3x8 = 24 divides p^2 – 1. <a href="https://mastodon.social/tags/maths" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#maths</a> <a href="https://mastodon.social/tags/PrimeNumbers" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#PrimeNumbers</a>
