NAME

       censuslookup - Search for triangulations in Regina's census databases

SYNOPSIS

       censuslookup isosig ...

DESCRIPTION

       This  utility  searches  for the given 3-manifold triangulations in the various census databases that are
       shipped withRegina.

       You should present the trianguations using their isomorphism signatures.  These are  short  text  strings
       that identify the triangulation uniquely up to combinatorial isomorphism (i.e., up to relabellings of the
       tetrahedra and/or their vertices).

       From the graphical user interface, you can view the isomorphism signature of a triangulation by switching
       to  the Composition tab in the triangulation viewer.  From Python you can fetch the isomorphism signature
       of the triangulation x by calling x.isoSig().  For  a  full  and  precise  specification  of  isomorphism
       signatures,   see   Simplification   paths   in  the  Pachner  graphs  of  closed  orientable  3-manifold
       triangulations, Burton, 2011, arXiv:1110.6080.

       All database matches (if any) will be written to standard output.

EXAMPLE

           example$ censuslookup fvPQcdecedekrsnrs dLQbcccajqs cPcbbbiht
           fvPQcdecedekrsnrs: 1 hit
               SFS [S2: (2,1) (3,1) (5,-4)] : #1 -- Closed census (orientable)

           dLQbcccajqs: 0 hits

           cPcbbbiht: 2 hits
               m004 : #1 -- Cusped hyperbolic census (orientable)
               L104001 -- Hyperbolic knot and link complements

MACOS X USERS

       If you downloaded a drag-and-drop app bundle, this utility is shipped inside it.  If you  dragged  Regina
       to the main Applications folder, you can run it as /Applications/Regina.app/Contents/MacOS/censuslookup.

WINDOWS USERS

       The  command-line  utilities  are  installed  beneath  the Program Files directory; on some machines this
       directory   is   called   Program   Files   (x86).    You   can   start   this   utility    by    running
       c:\Program Files\Regina\Regina 5.1\bin\censuslookup.exe.
