Description
Gives the number of irreducible factors of the Coxeter polynomial of the Dyck path over the rational numbers.
Here the Coxeter polynomial is by definition the Coxeter polynomial of the corresponding LNakayama algebra.
Code
For example for algebras with 7 simples:
z:=7;R:=BuildSequencesLNak(z);temp:=[];for i in R do Append(temp,[[i,Size(Factors(CoxeterPolynomial(NakayamaAlgebra(i,GF(3)))))]]);od;temp;

The bijection between Kupisch series of LNakayama algebras and Dyck paths in SAGE is due to Christian Stump and given by (in an example):

sage: def seq_to_Dyckpath(seq):
....:     return DyckWords().from_area_sequence([ i-2 for i in
reversed(seq) ][1:])

sage: X = [ [ [ 2, 2, 2, 1 ], 3 ], [ [ 3, 2, 2, 1 ], 2 ], [ [ 2, 3, 2,
1 ], 2 ], [ [ 3, 3, 2, 1 ], 2 ], [ [ 4, 3, 2, 1 ], 1 ] ]
sage: for seq,val in X:
....:     D = seq_to_Dyckpath(seq)
....:     print list(D), "=>", val
