## Abstract

The first occurrence of a string of 2*r* - 1
composite numbers between two primes
(denoted by *f(r)* and *f(r)* + 2*r*)
is tabulated for
*f(r)* in the range
2.6 × 10^{12}
< *f(r)* < 4.444 × 10^{12}.
This extends earlier computations in the range
*f(r)* < 2.6 × 10^{12}.
## Comments

A continuation of Brent
[19]
to 4.444 × 10^{12}.
