hmmmm ....

i'd better check the maths about that ....

indeed, there is a special issue of "Pour la Science" (the french 
translation
of the american "Science" magazine) that is entirely dedicated to 
Evariste Galois.
This has been highly advised to me, particularly because the 
explanations are cristal clear.
They maybe explain all the secrets to ECC ...

YG who should code more VHDL, otherwise F-CPU will become "Tired-CPU" :-P
