Solution

  • Ok now i understand how that work´s the first sigh is the distance in the lexicon the second is the number of sign which is copie and the third is the next sign.

    Example: <4|1|N> that means we are at the four A from left to right. The last A is the 4th sigh in the lexicon that stay for the 4 we can copie the N to because we have an A in the lexicon that is the 1 and the N stay for the next sign.
