What is claimed is: 1. A ceramic honeycomb filter comprising a porous ceramic honeycomb body having an inlet end and outlet end connected by adjacent inlet and outlet channels that extend from the inlet end to the outlet end of the ceramic body, the inlet and outlet channels being defined by a plurality of interlaced thin gas filtering porous partition walls between the inlet and outlet channels and by ceramic plugs, such that the inlet channel has an inlet ceramic plug at the outlet end of the ceramic body and the outlet channel has an outlet ceramic plug at the inlet end of the ceramic body such that a fluid when entering the inlet end must pass through partition walls to exit the outlet end, wherein the ceramic honeycomb body has at least one outer corner defined by the surface on the outside of the honeycomb and an inner corner opposite the outer corner defined by the surface within a channel, the outer corner having, a shape when viewed looking down the channels of the honeycomb, that is comprised of (i) at least two circular arcs wherein at least one of said circular arcs has a different radius of curvature than the other circular arc or arcs or (ii) a non-circular arc.
