A hexomino (or 6-omino) is a polyomino of order 6, that is, a polygon in the plane made of 6 equal-sized squares connected edge-to-edge. The name of this type of figure is formed with the prefix hex(a)-. When rotations and reflections are not considered to be distinct shapes, there are 35 different free hexominoes. When reflections are considered distinct, there are 60 one-sided hexominoes. When rotations are also considered distinct, there are 216 fixed hexominoes. (Wikipedia).
Hexomino game AI at different levels. (Like tetris, but with 6-block pieces.)
In this video, I showcase how Pierre Dellacherie's Tetris AI fares with a mixed tetromino+pentomino+hexomino piece set. It is insanely difficult even for a human. Let's see how Pierre Dellacherie's AI fares without any customizations. In addition to the 60 distinct hexominos, this particu

I define one of the most important constants in mathematics, the Euler-Mascheroni constant. It intuitively measures how far off the harmonic series 1 + 1/2 + ... + 1/n is from ln(n). In this video, I show that the constant must exist. It is an open problem to figure out if the constant is

Erik Demaine - New Ways to Fold a Cube from Paper - CoM Oct 2021
What shapes of paper can fold into a unit cube? This seemingly simple question has many interesting answers and open problems, depending on what type of folding is allowed. In particular, we’ll see a new way to fold a 3 × 3 square into a unit cube using horizontal, vertical, and diagonal c
