ERRATUM

In the article by V. P. Gromyko, “On a new criterion for the speciality of \(\pi d\)-groups with a prescribed number of classes of unattainable iso-ordered \(\pi d\)-subgroups,” published in DAN, vol. 151, no. 1, 1963, the following corrections must be made.

On p. 25, line 2, instead of \(>t\), read \(r \geq t\).

On p. 26, line 14, instead of Vesci AN BSSR, no. 2 (1963), read Vesci AN BSSR, no. 3 (1963).

On p. 26, line 19, the reference is missing: \(^{13}\) P. Hall, J. London Math. Soc., 3 (1928).
