... The irreducible polynomial is: z 8 + z4 + z3 + z + 1 Also uses degree-3 polynomials with coefficients from GF(28). I.e., each coefficient is represented as a byte. These are kept as 4 bytes (used for the columns) The polynomial used as a modulus is: M(x) = 00000001x4 + 00000001 or x4 + 1 (= x4 - 1) ...

... An oriented manifold is a (necessarily orientable) manifold M endowed with an orientation. If (M, o) is an oriented manifold then o(1) is called the fundamental class of M , or the orientation class of M , and is denoted by [M ]. Remark 3. Notice that since Z has exactly two automorphisms an orienta ...
