the solutions to the answers considered to have a copyright date of when
the problem was posed or when the solution was published? Note:
In the case of polydactylia, there are several areas that could be linked:
General including pictures, specific including breeds whose standards allow
it (eg Pixiebob) and associated pix,info and even more specific where a
specific cat is referenced as having it (eg Bingham Oddity who was a Russian

run off into several areas. Multiple points in both the text, and
the Problems/Answers need these links.
