\myheading{Galois Fields, GF(2)} \renewcommand{\CURPATH}{GF2} \leveldown{} \input{GF2/CRC/main} \input{GF2/GCM/main} \myheading{Important note} We've been taught in school that mathematics is all about counting objects (apples) or areas (geometry). But there are algebras (GF) which can't count objects, however, have enough useful features to use them practically. GF is one of them. \levelup{}
