This page contains notes about the status of the OEIS wiki. It provides a brief description of the wiki setup. It will also be used to announce changes in the structure of the wiki, so it may be useful to add it to your watchlist by clicking on the watch tab at the top of the page.

Users can create and modify discussion pages here. The discussion pages are a reasonable place to make comments about the structure of the wiki.

Do not use the discussion pages to suggest changes to OEIS sequence entries.

This is no longer required, but is strongly recommended. If this evolving statement causes you to want to change your username, send email to David, and I can make the change.

A few preliminary pages (most of these need to be updated!)

Sequence of the Day for August 28

A060295: Ramanujan's constant \scriptstyle e^{\pi \sqrt{163}} \,

262537412640768743
.999999999999250072597...

the fractional part of which has the simple continued fraction (A058292)

\cfrac{1}{{1} + \cfrac{1}{{1333462407511} + \cfrac{1}{{1} + \, \ddots}}} \,

The neat thing about this constant is that it is almost the integer 262537412640768744; indeed if an ordinary calculator could show just a few more decimal places than that it would eventually give up and just show this integer (the Mac OS X Calculator, for example, gives the answer as 262,537,412,640,000,000).
