Periodic sub-structure in radio emission from magnetars provides an observational link not only between magnetars and fast radio bursts, but across all classes of radio-emitting rotating neutron stars. The correlation between sub-structure periodicity and neutron-star rotational period can be used to determine an underlying period for fast radio bursts.
