Description
The number of torsionless simple modules in the linear Nakayama algebra corresponding to a Dyck path.
A module $M$ is called $r$-torsionfree in case $\operatorname{Ext}^i_A(D(A),\tau(M))=0$ for all $i=1,2,..,r$. A torsionless module is a 1-torsionfree module.
The number of simple 2-torsionfree (i.e. reflexive) modules is given by St001066The number of simple reflexive modules of the linear Nakayama algebra corresponding to a Dyck path.. The number of simple 3-torsionfree modules is given by St001063The number of 3-torsionfree simple modules in the linear Nakayama algebra corresponding to a Dyck path..
The correspondence between linear Nakayama algebras and Dyck paths is explained on the Nakayama algebras page.

# Pure combinatorial: count simple modules that are 1-syzygies (torsionless).
# S_i is a 1-syzygy iff S_i is projective (K[i] = 1) or ∃ M(j, l) with Ω(M(j, l)) = S_i.
# Ω(M(j, l)) = M(j+l, K[j]-l) when l < K[j] and j+l < n.
# So Ω(M(j, l)) = S_i = M(i, 1) iff j+l = i and K[j]-l = 1, i.e., l = K[j]-1 and j = i-K[j]+1.
