Abstract: A tile is a finite subset T of mathbb{Z}^n. It may or may not tile mathbb{Z}^n, in the sense of mathbb{Z}^n having a partition into copies of T. However, Chalcraft conjectured that every TA does tile mathbb{Z}^d for some d. In this talk, we will discuss some examples, and also a proof of the conjecture, recently obtained in joint work with Vytautas Gruslys and Ta Sheng Tan.
