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.
