%C A051799 4-dimensional pyramidal number, composed of consecutive 3-dimensional 
               slices; each of which is a 3-dimensional 12-gonal (or dodecagonal) 
               pyramidal number; which in turn is composed of consecutive 2-dimensional 
               slices 12-gonal numbers. - Jonathan Vos Post (jvospost3(AT)gmail.com),
