Following our paper [Fund. Inform. 136 (2015), 345--379],  we define a~horizontal mesh algorithm that constructsa~$\widehat{\Phi}_I$-mesh translation quiver  $\Gamma(\widehat{\CR}_I,\widehat{\Phi}_I)$ consisting of$\widehat{\Phi}_I$-orbits of the finite set $\widehat{\CR}_I=\{v\in\mathbb{Z}^I\; ;\;\...
