Let $\alpha(d,k,\mathbb{F})$ denote the maximum size of a $k$-nearly orthogonal set in $\mathbb{F}^d$. Over the real field, Füredi and Stanley showed that…

Let $\alpha(d,k,\mathbb{F})$ denote the maximum size of a $k$-nearly orthogonal set in $\mathbb{F}^d$. For the real field, the union of $k$ pairwise disjoint orthogonal bases gives…
