    "abstract": "The quantum mechanical motion of a relativistic particle in a non-continuous\nspacetime is investigated. The spacetime model is a dense, rationale subset of\ntwo-dimensional Minkowski spacetime. Solutions of the Dirac equation are\ncalculated using a generalized version of Feynman\u0027s checkerboard model. They\nturn out to be closely related to the continuum propagator.",
