Strong Trinucleotide Circular Codes

Table 2

(a) The four classes having each six -strong 20-trinucleotide circular codes. Each class is described by its pattern and the five codes of the permutations of the symmetric group on the pattern allow the other five -strong 20-trinucleotide circular codes of the class to be deduced. (b) The 16 classes having each 12 -strong 20-trinucleotide circular codes. Each class is described by its pattern and the 11 codes of the permutations of the symmetric group on the pattern allow the other 11 -strong 20-trinucleotide circular codes of the class to be deduced. (c) The eight classes having each 24 -strong 20-trinucleotide circular codes. In this case, each class is only described by its pattern as the other 23 -strong 20-trinucleotide circular codes are obtained with the 23 permutations of the symmetric group .
