The "Seed" $\mathcal S = (\mathcal I, \Gamma, \Pi)$
Consider a triple $\mathcal S = (\mathcal I, \Gamma, \Pi)$, where $\mathcal I$ is a compactified 4-sheeted branched cover of $\Bbb C$, $\Gamma \subset \mathcal I$ is a constellation (D'essin D'enfant in simpler cases), and $\Pi$ is a finite nonabelian piecewise isometry group. Specifically, let $\mathcal{O}_1, \dots, \mathcal{O}_4$ be four spindle orbifolds (topologically, Riemann spheres $\widehat{\mathbb{C}}$ each with two cone points). Let their union form the 2-complex: $$\mathcal{I} = \bigcup_{j=1}^{4} \mathcal{O}_j$$ These four surfaces intersect precisely along a 1-dimensional locus $\Gamma$, which serves as the 1-skeleton of the complex. Combinatorially, $\Gamma$ is a 4-regular octahedral graph ($|V| = 6$, $|E| = 12$). Geometrically, $\mathcal{I}$ is intrinsically parameterized within a bounding 3-dimensional cube, with the $6$ vertices (0-cells) of $\Gamma$ sinking into the interior, located exactly on the local coordinate planes $x, y, z = 1/2$. Let $P = \{p_{j,1}, p_...
