First my standard disclaimers: 1.) The web page design and layout for getting the Square 1 back to cube shape have been stolen directly from Christian Eggermont. My notes were very similar but I liked his presentation much better than mine. The only thing I have done to his notes was to rearrange the classification of shapes as to their 'distance' from cube shape. To see his original work please refer to: http://web.inter.nl.net/C.Eggermont/ 2.) I expanded on Andrew Arensburger's cube preserving formulas and also adopted his piece notation system. To see his original work please refer to: http://www.cfar.umd.edu/~arensb/Square1/ 3.) Some formula were revised and expanded upon from Richard Snyder's Square 1 Solution Book. Nice book but sometimes a bit cryptic. 4.) I know that there has to be some errors in my notes. If you find them please advise me so that I might make the corrections necessary. (Actually now that I think about it, I believe that in the Edge moves section there is a mistake where I say to turn the bottom 30deg in one direction but it would make an impossible Right turn... if you see this just turn the bottom the other direction... I'll try to find it and correct it asap) 5.) There are 2 or 3 pages of blank diagrams or unfinished notes that indavertantly got included. Please disregard anything that looks unusual... (hopefully that won't be every page you look at...) ;) Ok, so if you're not asleep by now you can hit http://128.192.40.238/pink/SquareList.html for the shapes list as to get from where you are now back to cube shape. There is a link at the bottom of that page to 3 PDF files. One to manipulate Corners, one for Edges and one for my initial thoughts on 2x2x2 cycling of Square 1 quadrants. I hope there is some info of use for somebody. And as always... feedback is very welcome. later all, _pink
