|(Wen pairs presented on a square grid)|
4 homogenous pairs of hexagrams (formed from identical trigrams) related through the complementarity relation
28 pairs of heterogenous hexagrams (formed from dissimilar trigrams) related through the figurative inversion relation
Xiantian arrangements are spatially defined with a clear pairing/ordering syntax
|xiantian magic square|
|traditional xiantian arrangement|
4 homogenous pairs of hexagrams form a diameter
28 hexagrams gird either side of this diameter
|internal view of 4 x 4 x 4 hypercube|
The hypercubic hexagram arrangement is well-defined but lacks ordering or pairing syntax entirely.
4 pairs of hexagrams comprise a cubic "core"
28 pairs of hexagrams form a "hull" around the core
Each vertex can also loop back to itself. These 8 loops constitute 4 pairs of homogenous* hexagrams. Loops at antipodal corners (e.g. (0,1,1) and (1,0,0) ) also designate Wen pairs.
