Cover illustration: A prime target for the synthesis of interwoven layered crystal structures is seven interwoven honeycomb (hcb) nets [see O'Keeffe & Treacy (2020), Acta Cryst. A76, 110-120]. No layer can be removed without breaking links, yet for any pair of nets (choose two colours) one is always above the other. Indeed, every coloured layer is `in the middle' of the structure, with three layers above it and three below.
