: It seems that strange numbers and strange plus numbers have been coined by CalmoSoft. The web seems to know nothing of them. 498 is a 'strange plus number' because 4+9 is prime and 9+8 is prime. Every sum of adjacent pairs of digits must be prime. --[[User:Chunes|Chunes]] ([[User talk:Chunes|talk]]) 08:13, 23 February 2021 (UTC) |
