- Number \(c_{\pi ,m}\) of alignments of length \(\ell =64\) with exactly m matches that are hit, by the contiguous seed (first column), by the Patternhunter I spaced seed (second column), and their respective difference (third column). The fourth column indicates the maximal number of alignments of length \(\ell =64\) with exactly m matches that could have been detected: when equality occurs with the first or the second column, the seed is then considered to be lossless: when this occurs, the background of the cell is pink
