Question: Table Compression Methods in Dragon Book

There is a section titled "Table-Compression Methods" at the end of the
chapter discussing lexical analysis in the newer dragon book. The intent
is to implement efficient transition tables by leveraging off of the
similarities among states, but the example is unclear to me. I don't
understand what is meant by "default" transitions or "special" states.
I would be grateful if some kind soul could provide a simple example
showing the appropriate structures.


Thanks in advance,
