When simply taking the limit "a" → 0 in the above inverse propagator, one recovers the correct continuum result. However, when instead expanding this expression around a value of "p"μ where one or more of the components are at the corners of the Brillouin zone (i.e. equal to /"a"), one finds the same continuum form again, although the sign in front of the gamma matrix can change. This means that, when one of the components of the momentum is near /"a", the discretized fermion field will again behave like a continuum fermion. This can happen with all "d" components of the momentum, leading to —with the original fermion with momentum near the origin included— 2"d" different "tastes" (in analogy to flavor).
