Let A"B"C" be the desmic product between ABC and A'B'C'. The triangles A"B"C" and ABC are perspective with center D', the triangles A"B"C" and A'B'C' are perspective with center D, the triangles  ABC and A'B'C' are perspective with center D", and the twelve points A, B, C, D, A', B', C', D', A", B", C", D" define a desmic structure.
