An error has been noted within Fig. 1[link] of the paper by Howard & Stokes (1998[Howard, C. J. & Stokes, H. T. (1998). Acta Cryst. B54, 782-789.]) . There is a group-subgroup relationship between I4/mcm (a0a0c-) and C2/c (a-b-b-), and this should be indicated on the figure by a continuous line joining the corresponding boxes. The corrected version of the figure is shown here.

A schematic diagram indicating the group-subgroup relationships among the 15 space groups tabulated by Howard & Stokes (1998[Howard, C. J. & Stokes, H. T. (1998). Acta Cryst. B54, 782-789.]). A dashed line joining a group with its subgroup indicates that the corresponding phase transition is required by Landau theory to be first order.

Keywords: perovskites; octahedral tilting; group-subgroup relationships.
