Notes:

- At this time the authors of this page do not have a matrix that achieves the stated determinant.
- Cannot achieve Barba bound as 177=2×89-1 is not a perfect square.
- This value was obtained by Farmakis and Kounias [FK] using an 88×88 Hadamard matrix of largest known excess. (The largest known excess is 792. The maximal excess is not known [FK].)
