Summary: Let \(\gamma_1, \gamma_2, \ldots\) be the imaginary parts of the zeros of the Riemann zeta-function in the upper half-plane, arranged in order of magnitude. This paper considers sums of the form
\[
\sum_{n=1}^N c_n\gamma_n, \tag{*}
\]
where each \(c_n\) has one of the five values \(-2,-1,0,1,2\), not all the \(c_n\) are zero, and at most one \(\vert c_n\vert\)has the value \(2\). In the theory of the distribution of primes, it is important to show whether or not any of the sums (*) are zero. In particular, if at most a finite number of these sums are zero, then we know that \(x^{-\frac12} \sum_{n\le x} \mu(n)\) is unbounded both above and below.

In this paper that sum of the form (*) which is closest to zero is exhibited for each value of \(N\) from 1 to 20. This minimal absolute value is compared with the value predicted from crude probability considerations. The agreement is so close as to suggest that one would not be likely to find a zero sum of the form (*) within a finite amount of computer time.
