In algebraic work, if you use a constant suffix__where
you always have, say,
33 and 53__you could treat them as 30 and 50 and come
out with the same algebraic
conditions. Therefore, if all these terminate with the
number two, we can drop off the two
and not affect the algebraic relationships. If we drop
off the number two in the last
column, they will all be zeros. So in the case of omnidirectional
closest packing of spheres,
the sequence will read; 10, 40, 90, 160, 250, 360, and
so forth. Since each one of these is
a multiple of 10, we may divide each of them by 10,
and then we have 1, 4, 9, 16, 25, and
36, which we recognize as a progression of second powering__two
to the second power,
three to the second power, and so forth.
