# [Discuss] Lychrel Numbers

Recently, there's a challenge "Anti-Lychrel Numbers": https://www.sololearn.com/learn/12390 Out of curiosity, I wiki the "Lychrel Number" and found that there's still no proof if there exists Lychrel Numbers for base10. However, there are some "Candidate Lychrel Number"s, which haven't been assured if they're Lychrel Numbers, ex. 196, 295, 394... see: https://en.m.wikipedia.org/wiki/Lychrel_number Now I have a plan, we can think about what kind of numbers can form a Lychrel Number. Maybe we can find if those Candidate Lychrel Numbers are Lychrel Numbers or not. The only rules I've thought of is: - Numbers only consists of 0~4 must not be a Lychrel Number And according to Wiki, the Lychrel Numbers with other bases are often: - Repeat some patterns, which make the number can't become palindrome Welcome to discuss and tell me any of your ideas ( ੭ु•ω•)੭ु
