Rhombic CAST existence with prescribed edge configurations and dihedral symmetry

Let nn be the polygon-order parameter, let the cases be those listed in Table~, and let ηmin\eta_{\min} and the edge configurations be the quantities specified in Tables~--. A rhombic CAST is a CAST whose prototiles are rhombs. Rhombic CAST conjecture. For every case in the listed table and for every nn, there exist rhombic CASTs with the specified edge configuration and inflation multiplier ηmin\eta_{\min} that yield individual dihedral symmetry DnD_n or D2nD_{2n}. The claim summarizes the paper's proposed existence pattern across all eight cases; examples are given, but the universal assertion for all nn and all cases remains unproved.
