  In addition to its connection with a standard confinement criterion, the
Kugo-Ojima function constitutes an indispensable component in a multitude of
applications in the gauge sector of QCD. In the present work we report on
preliminary results of an ongoing large-volume lattice simulation of this
special function. In particular, the volume-dependence of the data is studied
in detail, and a comparison with results obtained from Schwinger-Dyson
equations is carried out.
