Calculating more complicated quantum products (pdf).

Here are three pages of simple examples demonstrating the
main features of the rule in small examples. When we move a black
square... (eps). (eps). When we move a red square ... (eps).

A collection of 4 simple calculations. The first one is in
F(2,5;6). The next three in F(2,4;6). (eps).

A more complicated calculation in F(2,4;6). (eps).

A slightly different calculation in F(2,4;6) (very similar to
the one above). (eps).

A sample calculation in F(3,5;8). This is larger than the
previous examples. Occassionally I have skipped one or two steps. I
tried to warn the reader by writing 'skip' on the arrow.(eps).

A sample calculation in F(3,6;8). This example demonstrates
the movement of fillers. I could not fit it in one page. (eps) .(eps).
