This chart shows m (horizontal axis) neutral to n (vertical axis). The neutral numbers m with respect to n are colored orange (■) for semidivisors and yellow (■) for semitotatives. Non-neutral numbers (divisors, totatives, and units) are colored gray (■). See a page showing all the arithmetic relationships of m ≤ n to n. These other charts were generated in Mathematica 8 on 13 June 2014.
