Abstract
We examine the coefficients of the box functions in N=1 supersymmetric one-loop amplitudes. We present the box coefficients for all six point N=1 amplitudes and certain all example coefficients. We find for ``next-to MHV'' amplitudes that these box coefficients have coplanar support in twistor space.
