Abstract: Some properties of finite iterations of the Lévy C curve.

Read draft 3,

- PDF
`c-curve.pdf`

(about 606k, 50 pages) - LaTeX source
`c-curve-3.tar.gz`

(about 674k, and sig)

Also by plain HTTP or by FTP or by RSYNC if desired. The sig file is a Gnu PG ascii armoured signature generated from my key.

"Draft" here means believed correct as far as it goes but more material to be added. The LaTeX source uses PGF for the pictures.

The source `.tar.gz`

includes various generator and development
programs which are all
GPLv3 up. They're
mostly Perl and a bit rough. Some C code makes graphs for
Nauty. The document has
self-tests in Pari/GP and the
functions there are extracted to a `devel/c-curve-defines.gp`

which
is highly specific to the document but might be of interest for experimenting.
(Requires GP 2.9 up some things.) A big Pari/GP file has generating functions
for the various configuration counts.

See Math::PlanePath::CCurve for Perl code implementing curve coordinate calculations. The corresponding CCurve section of the PlanePath image gallery has some pictures.
