Unified Pattern — Bases — YANG, hexagram 15 (Da Zhuang, The Power of the Great — King Wen no. 34)
One of 256 distinct Unified Patterns — a 12×12 Jacquard construction where every cell's colour is read off a single hexagram of the Yi King, hexagram Da Zhuang, The Power of the Great. Binary numbering 0–63; in brackets, the traditional King Wen number.
Family Bases — YANG, one of the 8 admissible families (out of 15) in the system's classification — see the lexicon for how families are built and admitted.
The pattern's three colour classes, set independently — change one, the other two stay put.
One tint, read in light and dark — a luminance reading, not three colours with two greyed out.
Reading the cell, line by line
The 144 cells of the 12×12 cell fall into six levels of 24 cells, one per line of the hexagram. Where the line is solid (yang), the level takes its colours from the family's YANG grid; where it is broken (yin), from its YANG mutant grid. Count of each colour, level by level:
| Level | Line | Grid read | Colour 1 (violet) | Colour 2 (magenta) | Colour 3 (orange) |
|---|---|---|---|---|---|
| 1 | solid | YANG | 8 | 8 | 8 |
| 2 | solid | YANG | 8 | 8 | 8 |
| 3 | solid | YANG | 8 | 8 | 8 |
| 4 | solid | YANG | 8 | 8 | 8 |
| 5 | broken | YANG mutant | 8 | 8 | 8 |
| 6 | broken | YANG mutant | 8 | 8 | 8 |
| Whole cell | 48 | 48 | 48 | ||
The three colours are exactly balanced: 48 cells each. The cell is unchanged by reflection in the vertical axis, reflection in the horizontal axis, a half turn.
Hexagram 15 (King Wen no. 34) — The Power of the Great
Upper trigram ☳ Zhen (The Arousing, Thunder); lower trigram ☰ Qian (The Creative, Heaven).
Image
Thunder above Heaven: the image of the great's power. Considerable force rises to the very highest point, visible to all, capable of shaking whatever lies in its path. This is the figure of power at its peak, one that must learn to master itself precisely because it could sweep everything away. Thus the noble one walks no path but those in keeping with right conduct: great force without proper measure becomes its own ruin.
Judgement — Resonance
Influence amplifies until it becomes a force no longer contained. What begins as simple resonance can, if nothing comes to frame it, grow until it escapes all control. This line warns that power without discipline sooner or later turns against the one who wields it.
The full hexagram page: the six lines, its magic square and the other patterns built on it.
Same shape, other colourings
Two involutions leave this motif's shape unchanged and only permute its three tints — verified across every family and every hexagram in the corpus, not just this one: swapping the pairing used to read the hexagram (YANG/YANG-mutant ↔ YIN/YIN-mutant), and taking the hexagram's binary complement (63 − 15 = 48). Toggle them below; the tiling never changes, only the colours do.
