# Thread: how to get the value of GFILog (FF)

1. ## how to get the value of GFILog (FF)

Hi,
I need to implement Galois Field division in my application.
In this document GFILog (FF) and GFLog(00) is not defined.

Please suggest me how can I calculate the value of these?

Thanks
$\frac{\mathbb{Z}_2[x]}{(x^8 + x^4 + x^3 + x^2 + 1)}$
