Strong Trinucleotide Circular Codes

Table 3

The prefixes and suffixes of the pattern of the 28 classes of -strong 20-trinucleotide circular codes (Tables 2(a)–2(c)). For each pattern , the subset (resp. ) of consists of the letters (resp. ) that appear at least once in prefix (resp. suffix) position of the trinucleotides of . Similarly, the subset (resp. ) of consists of the diletters (resp. ) that appear at least once in prefix (resp. suffix) position of the trinucleotides of .
