WebOct 20, 2011 · Galois field is the name that engineers (and especially those studying error correcting codes) use for what mathematicians call a finite field. In applications, the most commonly used Galois field is GF ( 256), also called GF ( 2 8). Its elements can be thought of as polynomials of degree 7 or less with binary coefficients ( 0 or 1 ).
