This page is for changes since [AGZ21] was published. As of 9 March 2022, there is only one new existence result: In October 2021 Hadi Kharaghani and Thomas Pender sent the \(CW(341,16^2)\).
Theorem 6.6 of [AGZ21] uses the \(d=3\) case of Theorem 6.5. It was an oversight not to note that the same is true for any odd \(d\), so a stronger theorem is:
Theorem: Let \(q\) be a prime power. Then a proper \(CW((q^{2e+1}-1)/n,q^{2e})\) exists for all divisors \(n\) of \(q-1\) if \(q\) is even, and all divisors \(n>1\) of \(q-1\) if \(q\) is odd.
