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.

An account is necessary to contribute to the Wiki. To request an account, click here. There was a time when the username was required to be your Real Name. 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 July 10

(2 n  −  1) 32 n   − 1, n   ≥   1
{ 3, 81, 1215, 15309, 177147, 1948617, ... }
Simon Plouffe published a helpful list of odd zeta values from
ζ  (9)
up to
ζ  (2051)
with a precision of 1000 decimal digits—an older version of this list also covered
ζ  (3)
ζ  (5)
ζ  (7)
and is now available in separate files with more digits. You could hardwire these values in projects (e.g. RxShell (ZETA and RX.MATH)) where computing small odd
ζ  (2 n  +  1)
values on the fly is no option, because it would take far too long. The odd
ζ  (2 n  +  1)
values can be used to determine Euler’s constant
among other things. A060851 can then help to verify computed values for Euler’s
(usually referred to as
(gamma) or Euler–Mascheroni constant), Apéry’s constant
ζ  (3)
, or log 2 after dynamic changes of the chosen precision, e.g., Open Object Rexx NUMERIC DIGITS 500.
