Hexagram

A hexagram is any of the sixty-four sets of solid and broken lines used in the Chinese classic text I Ching. Each of these consists of two trigrams, and may be referred to either by its own name and number or as one trigram over another.

\n A hexagram (also known as "sexagram") is a six-pointed star. It is usually symmetrical, formed by two overlapping equilateral triangless. One version of the hexagram is the Star of David, a traditional Jewish symbol. Some cultures say that the triangle pointing downwards represents female sexuality and the triangle pointing upwards represents male sexuality. The combination represents unity and harmony. In alchemy, the two triangles represent the reconciliation of the opposites of "fire" and "water". The hexagram, like the pentagram, was and is used in practices of the occult as well as Satanism. The G₂ root system is in the form of a hexagram.
