1) If you want to see the enumeration of words associated with list L and contain exactly one pattern 123, using Theorem 1 in the paper, here are some samples:
2) If you want to see the minimal algebraic equations satisfied by the generating functions enumerating words with exactly r occurrences of each of the letters {1, ..., n} that contain exactly one pattern 123, for r=1, r=2, r=3:
3) If you want to see the recurrences (in operator notation) for our sequences enumerating words with exactly r occurrences of each of the letters {1, ..., n} that contain exactly one pattern 123, for r=1 and r=2:
