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.
