1. A method for determining the nucleotide sequence of a target polynucleotide, the method comprising the steps of:

  • generating from the target polynucleotide a plurality of fragments that cover the target polynucleotide;

    attaching an oligonucleotide tag from a repertoire of tags to each fragment of the plurality (i) such that substantially all different fragments have different oligonucleotide tags attached and (ii) such that each oligonucleotide tag from the repertoire comprises a plurality of subunits and each subunit of the plurality consists of an oligonucleotide having a length from three to six nucleotides or from three to six basepairs, the subunits being selected from a minimally cross-hybridizing set wherein a subunit of the set and a complement of any other subunit of the set would have at least two mismatches;

    sorting the fragments by specifically hybridizing the oligonucleotide tags with their respective complements, the respective complements being attached as uniform populations of substantially identical complements in spatially discrete regions on one or more solid phase supports and the respective complements being oligodeoxyribonucleotide N3'"'"'→

    P5'"'"' phosphoramidates or peptide nucleic acids;

    determining the nucleotide sequence of a portion of each of the fragments of the plurality; and

    determining the nucleotide sequence of the target polynucleotide by collating the sequences of the fragments.
