Welcome to the sphere packing database
This database has been created during my work
at the DFG-project
Prof. J.M. Wills
since November 1999. Our research concentrates on the investigation
of sphere packings under use of parametric density introduced by
Betke, Henk and Wills in 1994.
The database contains the densest sphere packings due to parametric
density we have calculated. Especially we have considered packings in the
face-centered-cubic lattice (fcc) with densest and second densest facets
(Groemer-packings). But also non-lattice packings are included in the
database, e.g. some Lennard-Jones clusters (see also
Cambridge Cluster Database
Birmingham Cluster Web).
To use this database you should start on the
. There you
can enter characteristica for the packings you are interested in.
After you have pressed the submit button, a list or packings which
match your criteria will be presented. If you click on the ID
of the packing, you will be lead to further information on this special
packing and some pictures. The usage is in detail described
If you have any suggestions or problems with the database, feel free to
I'm especially interested in packings of which you think, that
it is useful to calculate their parametric density and to compare them
to those in the database.
At last I want to thank
Dr. Achill Schürmann
Priv. Doz. Dr. Uwe Schnell for their help and useful suggestions to my
work on this project and the
Tjabo Kloppenburg for
help and ideas to
perl and other Unix-stuff.
I hope you get the information you are interested in...
