Dan Stearns and coherence

Quoting message 14367 :

<< (1) Mathematically speaking, the following graph A
is a chordoid. Chordoid theory don't apply only in
music. Why it is a chordoid? (Forgeting details)
it's because there exist a chordic generator C for
this graph A

0---O---O---O
/ \ / \ / \ / \
O---0---0---O---O
\ / \ / \ / \ /
O---0---0---O

And the chordic generator C is

0---O
/ \ / \
O---0---0

How? Refering to origin, the chord C may be
translated to take all the positions where one
of his node occupies origin (without rotation). >>

Could Dan Stearns or someone else give me more precision (message numbers
or subject titles). I'm very interested.

I would be happy if someone else have soon used chordic generator. Besides,
I would like to communicate these references to a young french student
making an academic work on relation between mathematics and music.
