p XVIII
A pattern language has the structure of a network. [...] Since the
language is in truth a network, there is no sequence which perfectly
captures it.

p XLI
[It is] possible to put patterns together in such a way that many
patterns overlap in the same physical space: the building is very
dense; it has many meanings captured in a small space; and through
this density, it becomes profound.

p XLIV
It is essential [...] that you pay attention to the possibility of
compressing the many patterns which you put together in the smallest
possible space. [It is] the only way of using a pattern language to
make buildings that are poems.
