Here we make the assumption that, once we get to the factor E + or E -, then the ratios of the 3-pair to 2-pair integrals is the same as if we calculated 4-pair to 3-pair integrals, and so on. We justify this by noting that this is interpreted as 'extending' a run of paired charged on neighboring polyelectrolytes, and that this extension reflects a criteria for the local bond directions that should become independent of the length of the run.
