Talk:Six cross-ratios

Useful sections
Sections "Six cross-ratios as Möbius transformations" and "Role of Klein four-group" contain useful material which I didn't see on "Cross-ratio" page. I suggest it be merged there before this article is deleted. Arcfrk (talk) 01:55, 12 June 2010 (UTC)


 * I copied the page to my userpage already. One possibility would be to replace the "symmetry" section at cross-ratio by this material. On the other hand, having so many sub-sections would clutter up the table of contents there. I am open to suggestions.  Tkuvho (talk) 20:21, 12 June 2010 (UTC)
