Maybe is correct The runlength or pattern length of a 6 bit LFSR should be rather than In one period of a maximal LFSR runs occurs for example a six bit LFSR will have 63 runs I suggest introducing hyphenation for clarity In one period of a maximal LFSR runs occurs for example a six bit LFSR will have 63 runs Exactly of these runs will be one bit long will be two bit long up to a single run of zeroes bit long and a single run of ones bit long
