Hi MathsIsFun;

There is only a single spelling error. Almost half way down the page "Amd."

To really investigate those stars would require a good sketcher type program. I quickly made a big mess with pen and paper.

What is the reason why for difference between the 6 and 7? Is it because they composite and prime?

A friend of mine used to draw these stars when she was younger.
