Algorithmic computation of principal posets using Maple and Python

We present symbolic and numerical algorithms for a computer search in the Coxeter spectral classification problems. One of the main aims of the paper is to study finite posets \(I\) that are principal, i.e., the rational symmetric Gram matrix \(G_I : = \frac{1}{2}[C_I+ C^{tr}_I]\in\mathbb{M_I(\mathb...
