Note added in proof

Two numerical values 104 appearing in Section 4 and 160 appearing in Section 4 and Appendix B (3) are the corrected ones respectively from the original incorrect 164 and 400, which were reported in the talk at the Seminar and written in Ref. [11].

In the text, the Penrose transformation is described as an expansion or structuration of two rhombohedra A6 and O6 so that the logical structure map be clearly seen. The obtained structure may be more clearly seen by noting that a point is transformed into a flower dodecahedron Fl60 consisting of 20 A6's (exactly speaking, a concave 60-hedron which looks like a dodecahedron each of whose 12 faces is a five-petalous flower) [20]. In this point of view, the tiling elements should not be regarded as A6 and O6 but as Fl60, F20, C = 2K30-O6 and O6.

Though the concept of self-similarity is useful, it may be better regarding it as a result of some local rule. Self-similarity, as a basic principle of a growing process, is a little curious: The situation may remind one a horoscope. If self-similarity is really the basic rule, an atom may have to know the position of its own star in deciding its position to attach. Therefore, it is expected that the basic rule is replaced by some local rule which leads the equivalent result.

In the discussion, Bennema gave a comment about the higher-dimensional crystallography. After that a very similar three-dimensional structure to the present model has been obtained as the projection of certain selected points of a six-dimensional simple cubic lattice to the three dimensional space [21]. The relation between the two models have not been known until the author figured it out [22].

Some two-dimensional Penrose-like tilings are obtained by similar hierarchical transformations. Some of them have pentagonal symmetry and some others have octahedral symmetry [20].
