The augmented truncated dodecahedron is Johnson solid
constructed by affixing a pentagonal cupola
to one of the decagonal faces of a truncated
dodecahedron such that the cupola's square faces are adjacent to the triangular faces of the truncated
dodecahedron. Since the affixed shape is a cupola
and not a pyramid, this solid does not represent a true
augmentation. The solid is illustrated above, together
with its skeleton and net.
