The sixty-four hexagrams

Every hexagram is two trigrams stacked: three lines below, three above. Eight trigrams squared give sixty-four. This page lists all of them, with the reading each one carries here.

How the grid works

The lower trigram sits underneath and is read first; theupper trigram sits on top. Each trigram is three lines, counted from the bottom up, and each line is either solid (yang) or broken (yin).

The classical names run the two images together, upper first: 水雷 is water over thunder, 火天 is fire over heaven. Where a hexagram is made of two identical trigrams, it is named after the trigram itself — 坎为水 rather than 水水 — which is why those eight read differently from the rest.

The numbers are the King Wen sequence, the traditional order used for divination. It is not binary order: the sixty-four are arranged in pairs that turn into one another, which is why 3 and 4 sit together and 11 and 12 do.

This site derives the whole table from the eight trigrams rather than transcribing it, and the tests check the derived names against the classical ones for every entry — so a typo in one cell cannot survive a build.

A hexagram on this page is a reference entry. To get one for a question you are actually asking, throw the three coins — that reading also explains the moving lines, which are the part that changes.
