Outlines the main provisions of the calculation of the stability of statically indefinable systems of regular structure. A planar structure with an external contour in the shape of a regular hexagon and under the action of nodal radial compression forces is considered. An analysis of the stability of the equilibrium state of the core structure is performed and the full range of numerical values of the instability parameter of the system is determined.

Keywords: core structure, regular hexagon, hinge system, characteristic polynomial, triangular panel
