    It was recently (2011) discovered that there is a gap in a 1974 paper by Szenthe that we use. This gap has been now been closed in a paper by K.H. Hofmann and myself.

    The following result should have been included right after 3.5. It is an easy consequence of what we prove in the paper.
    Proposition. Let \(\varphi\) be an (abstract) homomorphism between topological polygons \(\mathfrak P\) and \(\mathfrak P'\). If the restriction of \(\varphi\) to the point space is continuous, then \(\varphi\) is continuous.

    It was recently (2011) discovered that there is a gap in Szenthe's 1974 paper [43, Thm.4]. This result is used in our paper. This gap has been now been closed in a paper by K.H. Hofmann and myself.

    Thm. 3.3.8 is not quite right: the point, line and flag space of a 5-dimensional compact hexagon may well be a product. The mistake occurs when I calculate with the Steenrod squares. This has no further consequences in the thesis.

    This is the first paper where the X-ray diffraction pattern for a finite quasicrystal was explicitly computed. The numerical results match the experimental data very well. I wrote the Fortran programs.
