Talk:Ormiston pairs

Should Ormiston pairs be disjoint?

Does anyone know the answer to this?

I'd previously assumed they should be - though it makes no difference if they are or not when considering numbers up to 10 million.

However, it does make a difference for numbers up to 100 million - there are 34,901 pairs in total of which 34,876 are disjoint. --PureFox (talk) 16:36, 31 January 2023 (UTC)

I don't see anything in the definition used here which requires them to be disjoint. --Rdm (talk) 16:59, 31 January 2023 (UTC)
