## Abstract

We describe a computation which shows that the Riemann zeta function
has exactly 75,000,000 zeros of the form
*sigma* + i.*t*
in the region 0 <*t* <32,585,736.4;
all these zeros are simple and lie on the line *sigma* = 1/2.
(A similar result for the first 3,500,000 zeros was established
by Rosser, Yohe and Schoenfeld.)
Counts of the number of Gram blocks of various types and the number of
failures of "Rosser's rule" are given.
## Errata

1. Page 1361, line -9 (not counting footnotes):
replace *H(10)* by *H(15)*.
2. Page 1362, equation (2.3): replace
*B*_{2k} by |*B*_{2k}|.

3. Page 1362, two lines after equation (2.3):
the bound on |*r*_{n}(t)|
is incorrect.

(The error is only significant for small *t*
and did not affect the computation of zeros of the zeta function.)

## Comments

For an extension of the computation to the first
2 × 10^{8}
zeros see Brent, van de Lune, te Riele and
Winter [70, 81].
Wedeniwski's
*ZetaGrid*
project, using essentially the same algorithm on more than 600 computers,
has pushed the bound past
10^{13} zeros.
