A correction is made to the article by Oishi-Tomiyasu [Acta Cryst. (2013[Oishi-Tomiyasu, R. (2013). Acta Cryst. A69, 603-610.]), A69, 603–610].

Section 2 of the article by Oishi-Tomiyasu (2013[Oishi-Tomiyasu, R. (2013). Acta Cryst. A69, 603-610.]) starts with the following sentence: `Any crystallographic group G is represented as the semidirect RG  ×L, where RG is a point group of G and L is the lattice …'. The phrase `semidirect RG  ×L' should be replaced by `group extension of L by RG'. This mistake does not affect the other parts of the article.
