Addendum: On the statistical analysis of the first digits of the Feigenbaum constants

The block entropies computed by lumping and gliding are calculated for the binary expansions of the Feigenbaum constants α and δ , and for 2 . Small but significant deviations from randomness are revealed for the binary expansions of the Feigenbaum constants α and δ , supporting the conclusions of the previous relevant work by the authors.
