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.
