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.*

Szenthe's 1974 paper [43, Thm.4]. This result is used in our paper.

Compact polygons.

Errata.

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.
