"Pattern of Signs" - two uploads

I have just posted two pdf files concerning the "Pattern of Signs" post I made earlier in March (here is the link: Pattern of signs), in which I prove the claims and explain the patterns noted in that post. Here are the links to the two files (the contents of the two files are the same, but one is suitable for reading on the screen, and the other one is suitable for printing):

• Pattern of signs - screen version
• Pattern of signs - print version

Actually, these links lead to the Google Docs versions of the two articles, but the articles can be downloaded as pdf files by clicking on an appropriate button at the top.

I look forward to observations from readers.
