All Conceptual ellipses (CE)     
                      Formula: harmonic "h"     

h = 2(A² - A)

h = (p - 1) / T

h = (i² - 1)/2

h = i₂ + i

h = i₃ + 1

h = i₄ - 1

h = i₅ - i

h = i₆ - i₂


h = Sum of one series of
Iteration Increments "inc."

(In the BHE Tables the repeating series is
blue highlighted.)
