1 Correction to: Eur. Phys. J. Spec. Top. https://doi.org/10.1140/epjs/s11734-022-00510-z

In this article Eqs. 2 and 3 have been incorerectly displayed; they should have appeared as shown below. The original article has been corrected.

$$\begin{aligned}&n_{i}^{\mathrm{cnf}} = \left( \begin{array}{c} N_{\mathrm{TOT}} \\ N_{A_{i}}, N_{R_{i}}, N_{M_{i}} \end{array}\right) = \frac{N_{\mathrm{TOT}}!}{N_{A_{i}}! N_{R_{i}}! N_{M_{i}}!}. \end{aligned}$$

$$\begin{aligned}&\sum _{i=1}^{N_{\mathrm{FS}}} n_{i}^{\mathrm{cnf}} = \sum _{i=1}^{N_{\mathrm{FS}}} \left( \begin{array}{c} N_{\mathrm{TOT}} \\ N_{A_{i}}, N_{R_{i}}, N_{M_{i}} \end{array}\right) = 3^{N_{\mathrm{TOT}}}. \end{aligned}$$
