Needs more wikilinks by persons who know which mathematical articles we've got and what they're called. Could use more pictures of diagrams?--Thomas Wright Sulcer 04:18, 19 April 2010 (UTC)

Wow! Looks impressing. (I have only a slight idea of this matter.) Boris Tsirelson 06:11, 19 April 2010 (UTC)
You could also add an external link from WP to here (as I did for "plane" for instance); it does not add google juice, but can add readers. Boris Tsirelson 06:21, 19 April 2010 (UTC)
Thanks Boris!!! I no longer have a Wikipedia account but feel free to add the link from WP. The two equations are from WP and some of the proof-logic from WP is here, rewritten, but other than that I'd say it's 90% new.--Thomas Wright Sulcer 11:24, 19 April 2010 (UTC)
Could you forget that WP can be edited by everyone? Anyway, I did. By the way, I see, you did not use your sandbox for preparing it. I wonder, did you write all of it first on your computer, locally? Boris Tsirelson 12:21, 19 April 2010 (UTC)
