non-symmetrical topologies like the Diamond unit cell. using the minimum number of cells is essential to estimate the correct stiffness matrix. Overall. the study provides insights into the effect of the number of cells on the mechanical properties of cellular structures and proposes an algorithm for stability analysis. The findings can be useful for designing and optimizing cellular structures for various applications.
