 +   <hidden TTP11-06  On Epsilon Expansions of Four-loop Non-planar Massless Propagator Diagrams > We evaluate three typical four-loop non-planar massless propagator diagrams in a Taylor expansion in dimensional regularization parameter $\epsilon=(4-d)/2$ up to transcendentality weight twelve, using a recently developed method of one of the present coauthors (R.L.). We observe only multiple zeta values in our results. </hidden>
