The zero-Hecke algebra of the symmetric group can be obtained as a deformation of the symmetric group, and conceived of as the algebra of anti-sorting operators. While the representation theory of this algebra is well-understood, it was not until recently that formulae for minimal idempotents to generate the projective modules were found. I will present at least one construction for these idempotents.
