This is important because burst errors are common transmission errors Crc Error Detection And Correction Example Richardson, Andrew (17 March 2005).
Such a polynomial has highest degree n, i.e. some subset of j consecutive bits for j < k. Improved 64-bit Cyclic Redundancy Check for Protein Sequences" (PDF). The length of the remainder is always less than the length ofthen so as to balance the maximal total blocklength with a desired error detection power.
