ambrus:

Oh, I didn't expect an explanation. But the field is so foreign to me, that it was kind of like: "Oh, you have this hard problem? Just use Kenlar Blurfle, and you'll see that the obvious answer is 42". A line or two of context would've been helpful. ;^D Of course, then I wouldn't have had the fun of exploring mathworld a bit.

Two books come into my mind that explain finite geometry - both are suitable for beginners as they don't have much prerequisites:

• Hraskó András (editor), Új matematikai mozaik. TypeTEX Kiadó, Budapest, 2002.
• Reiman István, A geometria határterületei

Great <sigh> now I'll have to add "Learn Hungarian" to my long list of ToDos, so I can read them! ;^)
