In 2000, Wieland proved that Alternating Sign Matrices have dihedral
symmetry by introducing an operation called gyration which implements a
rotation. Recently, Cantini and Sportiello introduced a generalization of
gyration and used it to prove the Razumov-Stroganov conjecture, thus
confirming the numerical evidence for the relation between a particular
XXZ Hamiltonian, Alternating Sign Matrices, and Fully Packed Loops. We
will give an overview of the proof, giving particular attention to the
role of gyration.
