1. Congruence Relation

   Linked via "vector congruences"

   if and only if the Euclidean distance $d(\mathbf{v}1, \mathbf{v}2)$ is an integer multiple of $N_T$, and the angular separation between the constituent vector components, when projected onto the fourth spatial axis ($\psi$), is a multiple of $\pi/6$.
   This latter requirement, that the angular displacement must follow a specific fractional multiple of $\pi$, is what differentiates the Tectonic Modulus from simpler [vector congruences](/entries…
