Figure 6.

Large combinatorial libraries of structure-free DNA sequences are constructed by linking small numbers of words together in a combinatorial fashion. The table above illustrates the number of tandem word sequences that can be created (lower right triangle in each table box) from a small number of words (upper left triangle in each table box). For each box, the number of tandem words linked together to form each sequence variant is listed across the top of the table whereas the number of word variants at each tandem word position is listed down the rows.
