! Airos recurrent sequence x^3 = 13 - 8x, Dudon 2008
! Eq-b of fourths, and septimal minor thirds with harmonic 7ths :
! 8(4 - 3x) = 3x^3 - 7 = (32x^3 - 56x)/13
! Airos fourths of 494.4315 c. (approx. 640/481),
! cycle here starting from the neutral sixth (A-koron = 723/445)
! -c with the 13th harmonic : (13 * 890) - 9503 = 2067, etc.
