Talk:3 (number)

Only prime p, where p and p-1 are both prime

Do we really needs this? I don't find anything particularly special about that property. This is the first time I have ever heard it even mentioned. David Tornheim (talk) 16:56, 22 October 2017 (UTC)[reply]

When it talks of "Three is an important number for many cultures", it is talking rubbish. It is very easy to make the case that two is far more important in many early cultures (but I wouldn't even bother to say that). Macdonald-ross (talk) 14:40, 3 November 2022 (UTC)[reply]
