I tried a few search engines and got the best results from Googol, http://www.googol.com/. I found information on Archimedean duals at http://www.georgehart.com/virtual-polyhedra/archimedean-duals-index.html and at http://www.queenhill.demon.co.uk/guy/articles/AHD/AHD.htm.
For "Cairo tesselation" I was less successful. I found a game called the The Cairo Bead Game which is played on a tessellated game board, but I am not sure if this what you are calling the Cairo tesselation. The site is http://home.flash.net/~markthom/html/cairo_bead_game.htmlI hope this helps,
