title: A tetrahedral representation of poly-codon sequences and a possible origin of codon degeneracy.
abstract: A novel and interesting representation of codon space is introduced in which the 64 codons are grouped and re-arranged as vertices in a tetrahedral lattice. Amino acids are then assigned to the lattice in a suggestive way which, when combined with earlier work, leads to an interesting speculation on the origin and development of the genetic code.
