NAME
sigcensus - Form a census of splitting surface signatures
SYNOPSIS
sigcensus order
DESCRIPTION
Forms a census of all splitting surface signatures of the given order
(the order is the number of quads in the resulting splitting surface).
The signatures will be written to standard output, one per line,
followed by a count of the total number of signatures found.
Each signature will be output precisely once up to equivalence.
Signatures are considered equivalent if they are related by some
combination of:
· relabelling symbols;
· rotating an individual cycle;
· inverting an individual cycle (i.e., reversing the cycle and changing
the case of each symbol in the cycle);
· reversing all cycles without changing the case of any symbols.
Warning: Currently upper-case symbols in signatures are not
supported; this program will only output signatures whose symbols are
all lower-case. Hopefully this deficiency will be removed in future
versions.
