Talk:Strange numbers

From Rosetta Code

is 0 strange

For that matter, are all the 1-digit numbers 1..9 strange? (I assumed they are, trivial change for me if not). --Pete Lomax (talk) 15:54, 23 February 2021 (UTC)

As the definition currently stands, I would say that no single digit number is strange because no digit of such a number has a neighbor. However, there would be some sense in augmenting the definition so that single digit primes are strange (i.e they would have a putative left neighbor of '0') though, of course, 0 itself would still not be. --PureFox (talk) 17:00, 23 February 2021 (UTC)
