Or, should solutions treat zero as a special case? -- [[User:Gerard Schildberger|Gerard Schildberger]] ([[User talk:Gerard Schildberger|talk]]) 22:12, 25 January 2020 (UTC)
:Zero is not a positive integer. The Möbius function is undefined at zero. No need to special case it. I don't see any examples that show a Möbius number for zero. Which ones are showing a value at zero? The only example that shows ANYTHING for an input of zero is the REXX example, and while that's a little odd, I wouldn't count it as wrong, as it specifically states that "bullet (•) to signify that a "null" is being shown (for the 0th entry)" ¯\_(ツ)_/¯ If REXX can't easily skip over zero, I'm not going to hold that against it. --[[User:Thundergnat|Thundergnat]] ([[User talk:Thundergnat|talk]]) 22:51, 25 January 2020 (UTC)
