I. J. GOOD. ‘A new formula for cumulants.’
Henryk Minc has pointed out in correspondence that Equation (12), which was a corollary of Theorem 2, does not agree with the computed values of Schur's matrix ω(rs) given by Graham and Lehmer (1976). In the course of the ‘proof’ I made the error of assuming that , overlooking that s could be a multiple of m, so that the sum can also equal m. Since this was the only error, the statement of Theorem 2 is correct modulo m. In particular it shows that perm(ωrs) ≡ 0 (mod m) but this result is much weaker than the results obtained by Graham and Lehmer.
Theorem 1 is unaffected by this error, and moreover has since been proved again by Groeneveld and van Kampen (1977).
