Query: Low-lying $s=+1$ Pentaquark states in the Inherent Nodal Structure
  Analysis   The strangeness $s=+1$ pentaquark states as $qqqq\bar{q}$ clusters are
investigated in this letter. Starting from the inherent geometric symmetry, we
analyzed the inherent nodal structure of the system. As the nodeless states,
the low-lying states are picked out. Then the S-wave state $(J^P, T)=
({{1/2}}^{-}, 0)$ and P-wave state $(J^P, T)= ({{1/2}}^{+}, 0)$ may be the
candidates of low-lying pentaquark states. By comparing the accessibility of
the two states and referring the presently obtained K-N interaction potential,
we propose that the quantum numbers of the observed pentaquark state
$\Theta^{+}$ may be $(J^P, T)=({{1/2}}^{+}, 0)$ and L=1.
