Sorry to be late in responding -- I've been on the road.
There's a tutorial on ferrites on my website. Select the two
documents about RF interference. One is directed to audio, but has
the best tutorial material. The other is the PowerPoint for a
presentation I did to our local ham club last spring.
Those numbers are Fair-Rite material numbers. Fair-Rite makes
nearly all of the ferrites sold as new parts in the ham market.

Once you've studied my tutorials, you may want to study data
sheets for the various materials on the Fair-Rite website. They
have an excellent pdf catalog, which you can download. Google to
find their website. There are other good companies making ferrite
parts, but they haven't found their way into the ham radio world
(except as unidentified surplus parts).
