Abstract
We report on an ongoing project to parametrize the Fixed-Point Dirac operat or for massless quarks, using a very general construction which has arbitra rily many fermion offsets and gauge paths, the complete Clifford algebra an d satisfies all required symmetries. Optimizing a specific construction wit h hypercubic fermion offsets, we present some preliminary results.
