Notes on a strongly aperiodic monotile in
Chaim Goodman-Strauss
We provide a clearer presentation of the Chair44 monotile, a new strongly aperiodic monotile in three-dimensional Euclidean space .
The {\em 4DLO} and other tubing models of symmetry
Chaim Goodman-Strauss, Eugene Sargent
The {\em Four-dimensional Light Orchestra} or {\em 4DLO} was an interactive sculpture at the National Museum of Mathematics (MoMath) from November 20, 2025 through January 2026, il…
Remark on Pascal's Triangle
Chaim Goodman-Strauss
Through a series of elementary exercises, we explain the fractal structure of Pascal's triangle when written modulo using an 1852 theorem due to Kummer: A prime divides $\d…
A chiral aperiodic monotile
David Smith, Joseph Samuel Myers, Craig S. Kaplan +1
The recently discovered "hat" aperiodic monotile mixes unreflected and reflected tiles in every tiling it admits, leaving open the question of whether a single shape can tile aperi…
A Coloring Book Approach to Finding Coordination Sequences
C. Goodman-Strauss, N. J. A. Sloane
An elementary method is described for finding the coordination sequences for a tiling, based on coloring the underlying graph. We illustrate the method by first applying it to the…
Strongly aperiodic subshifts of finite type on hyperbolic groups
David Bruce Cohen, Chaim Goodman-Strauss, Yo'av Rieck
We prove that a hyperbolic group admits a strongly aperiodic subshift of finite type if and only if it has at most one end.
