[HTML][HTML] Counting n-cell polycubes proper in n− k dimensions
G Barequet, M Shalah - European Journal of Combinatorics, 2017 - Elsevier
A d-dimensional polycube of size n is a connected set of n cubes in d dimensions, where
connectivity is through (d− 1)-dimensional faces. In this paper, we develop a theoretical …

The perimeter of proper polycubes
S Luther, S Mertens - arxiv preprint arxiv:1705.03688, 2017 - arxiv.org
We derive formulas for the number of polycubes of size $ n $ and perimeter $ t $ that are
proper in $ n-1$ and $ n-2$ dimensions. These formulas complement computer based …

Automatic proofs for formulae enumerating proper polycubes
G Barequet, M Shalah - Electronic Notes in Discrete Mathematics, 2015 - Elsevier
We develop a general framework for computing formulae enumerating polycubes of size n
which are proper in n− k dimensions (spanning all n− k dimensions), for a fixed value of k …

Polycubes with small perimeter defect
In this paper, we consider enumeration of d-dimensional polycubes, whose perimeter
(defined as the number of empty cells neighboring the polycube) has a fixed deviation from …
