Let $([d],\mathcal{L})$ be a covering clutter, let $s$ be its magic subspace, and let a magic permutation be a permutation of $[d]$ realizable by a positive point in $s$. For a per…

Let $M_n$, $S_n$, and $P_n$ denote the counting functions for the magic squares considered in the paper, with parameter $n$. Nonpolynomiality conjecture. The functions $M_n$, $S_n$…

Let $(p,q,r)$-boards be the three-dimensional boards considered in the paper, and let a board be Cartesian bi-magic when it admits a Cartesian bi-magic labeling. Cartesian bi-magic…
