Arithmetic Relationship Map.

by Michael Thomas De Vlieger, 2009, revised and condensed 13 August 2014, St. Louis, Missouri.

This chart shows the arithmetic relationship of m (horizontal axis) to n (vertical axis). Divisors are shown in red () and totatives in gray (). The number m = 1 is both a divisor and a totative and is colored purple (). The neutral numbers m with respect to n are colored orange () for semidivisors and yellow () for semitotatives. The regular numbers m with respect to n are the unit, divisors, and semidivisors (). Click here for a page that shows a chart that extends to n = 865, and here for an image that extends n to 2520. These other charts were generated in Mathematica 8 on 13 June 2014.
