Regina Raw Signature Directory
2
------------------------------
4
This directory contains a census of splitting surface signatures as
5
generated by Regina. For space considerations only signatures of order
6
at most 7 are included.
8
Note that the directory above this includes topology data files
9
containing the enclosing triangulations of signatures from this census
10
satisfying various constraints.
12
Signature files within this directory are of the following types.
15
These are plain text files containing all splitting surface
16
signatures of a given order. Each individual signature is written
19
For brevity, brackets are omitted and cycles are separated by periods.
20
For instance, the signature '(aab)(bc)(c)' is written as 'aab.bc.c'.
23
These are bzipped signature files, used when the raw signature files
24
are very large. These files can be uncompressed using the bzip2
25
utility which is available from http://sources.redhat.com/bzip2/
26
or your favourite GNU/Linux distribution.
