Anything that fits is kept; anything that does not is discarded.

Perhaps their most spectacular discovery was that musical ; a string one-half as long produces an extremely harmonious note to the first, now called the octave.
This number symbolized unity arising from multiplicity. A single point corresponds to 1, a line to 2 (because a line has two extremities), a triangle to 3, and space to 4. The Pythagoreans recognized the existence of nine heavenly bodies: Sun, Moon, Mercury, Venus, Earth, Mars, Jupiter, Saturn, and the so-called Central Fire. The square numbers (1, 4, 9, 16,…) were arranged in squares, and the triangular numbers (1, 3, 6, 10,…) were arranged in triangles ().
So important was the number 10 in their view of cosmology that they believed there was a tenth body, Counter-Earth, perpetually hidden from us by the Sun. This terminology remains in use to the present day.
In these forms of number mysticism the letters of an alphabet are assigned numbers by some rule, typically in Greek has the numerological value 888, three repetitions of the number 8, which is often considered auspicious.
