... 1. Starting with a block of ones, d consists of blocks of ones, interweaved with blocks of zeros. Let n 0 be the number of blocks of zeros and n 1 be the number of blocks of ones. Con- sider the ... (using very large values of M), they rely on the use of mean square error distances instead of the Hamming dis- tance. Thus, their study is not covered by the class of me...
