A note on free determinantal hypersurface arrangements in $\mathbb{P}^{14}_{\mathbb{C}}$

In the present note we study determinantal arrangements constructed with use of the $3$-minors of a $3 \times 5$ generic matrix of indeterminates. In particular, we show that certain naturally constructed hypersurface arrangements in $\mathbb{P}^{14}_{\mathbb{C}}$ are free.

Generic projections of the $\mathrm{H}_{4}$ configuration of points

In the present note we give an example of a finite set of points in $\mathbb{P}^{3}$ which has the so-called geproci property, but it is neither a grid nor a half-grid. This answers a question on the existence of such sets rised by Pokora, Szemberg and Szpond [arXiv:2010.08863].
