Hexagrams

The hexagram is the main I Ching entity. It is made up of two trigrams, referred to as "lower" and "upper". Hence, six lines comprise a single hexagram. Hexagram lines are ordered from bottom to top: the bottom line of the hexagram is referred to as the first line. The structure of the 64 hexagrams is shown in table .
