| Jan 15, 2016 at 23:12 | comment | added | kodlu | sorry, to clarify that result is for the general partial hadamard matrices. | |
| Jan 15, 2016 at 21:51 | comment | added | Simd | I meant the part directly following "the best result I have found is the following" where you quote some result when $n\leq \frac{t}{2}-t^{\frac{113}{132}+\varepsilon}$. Is that not to do with Hadamard partial circulant matrices after all? | |

| Jan 15, 2016 at 21:43 | comment | added | kodlu | @dorothy: do you mean the computational results? It's from a computational stackexchange group . I added the link to the question. | |
| Jan 15, 2016 at 20:48 | comment | added | Simd | Can you give a reference for the result you refer to in your Edit? | |

| Jan 15, 2016 at 20:46 | comment | added | Simd | I just posed a very similar question but have deleted it after seeing this. It turns out that for $n/2$ by $n$ Hadamard partial circulant matrices with $n=4,8,12,16,20,24,28$ the numbers of these matrices is: $12,40,144,128,80,192,560$. There exist $0$ for $n=32$ but more than $0$ for $n=36$. | |
