A correction is made to the article by Oishi-Tomiyasu [Acta Cryst. (2013), A69, 603–610].
Keywords: systematic absences; powder auto-indexing; algorithm.
Section 2 of the article by Oishi-Tomiyasu (2013) starts with the following sentence: `Any crystallographic group G is represented as the semidirect RG ×L, where RG is a 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.
