Here is one of my projects: IMSLP Orchestra to do world premiere recording of Symphony by Franz Asplmayr.

I graduated from Wayne State University with a bachelor's degree in Film Studies in 2008. In 2004, I wrote for WSU's student newspaper, The South End, an article on the celebration for the 100,000th sequence to be added to the OEIS, A100000.

 Sequence of the Day

## Sequence of the Day for July 10

A060851:
 (2 n  −  1) 3 2 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)
and
 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
 C0
among other things. A060851 can then help to verify computed values for Euler’s
 C0
(usually referred to as
 γ
(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.

• A239797 Decimal expansion of ${\frac {\sqrt {3}}{\sqrt[{3}]{4}}}$ .
• A238271 Decimal expansion of $\sum _{n=1}^{\infty }{\frac {\mu (n)}{3^{n}}}$ .
• A237042 UPC check digits.

• A234522 Decimal expansion of ${\sqrt[{4}]{7}}-{\sqrt[{4}]{5}}$ .
• A233748 Number of graphs on n vertices with edges colored with at most four interchangeable colors under the symmetries of the full edge permutation group.
• A232499 Number of unit squares, aligned with a Cartesian grid, completely within the first quadrant of a circle centered at the origin ordered by increasing radius.
• A231963 Concatenate $n$ with its UPC check digit.
• A230624 Numbers $n$ with property that for every base $b\geq 2$ , there is a number $m$ such that $m+s(m)=n$ , where $s(m)$ is the sum of digits in the base $b$ expansion of $m$ .

## Sequences in the News
