There are now hexagrams in Unicode:

  http://www.unicode.org/charts/PDF/Unicode-4.0/U40-4DC0.pdf

The order seems strange, but I guess it's the other of the
traditional orders present in I Ching (as I remember was
explained by Martin Gardner in his venerable SciAm column),
the other being just an order disctated by the binary expansions
of the integers 0 - 63.

But what is this:

"Tai Xuan Jing Symbols" ???

Clearly, http://www.research.att.com/projects/OEIS?Anum=A007089
should contain a link there.


So, if there are so much free space among the upper half
of the 32-bit codepoints, then why not suggest a specific
range for the 52 or (53/54) Genji-mon also?
Those who have not followed this thread from the start,
please follow the John Fiorillo's and Kazuhiro Kunii's links from
http://www.research.att.com/projects/OEIS?Anum=A000110


After having get that approved, it would natural to suggest
other gems from the combinatorial cornucopia, all the denizens
of the Catalania upto a certain size, etc.
(Am I joking or not? I don't know. But some people seriously want
Klingon script to be approved into Unicode.)



Terveisin,
