Abstract: We extend recent studies of the effects of quark–gluon vertex dressing upon the solutions of the Dyson–Schwinger equation for the quark propagator. A momentum delta function is used to represent the dominant infrared strength of the effective gluon propagator so that the resulting integral equations become algebraic. The quark–gluon vertex is constructed from the complete set of diagrams involving only two-point gluon lines. The additional diagrams, including those with crossed gluon lines, are shown to make an important contribution to the DSE solutions for the quark propagator, because of their large color factors and the rapid growth in their number.
