F_ba Decomposition of the basenumber in its prime factors.
F_po Decomposition of the palindromic nonagonal.
Note : a palindromic nonagonal will always be divisible by its basenumber when this
last one is 'odd'. With 'even' basenumbers you'll notice that the nonagonals
are always divisible by half their basenumbers.
To reconstruct the nonagonals you must take into account the green together with
the purple prime factors but not the black 2.
