2026_03_19_chojecki: A note proving that the sifted set of Problem 25 has natural, hence logarithmic, density when the reciprocals of the moduli are summable or the moduli are pairwise coprime; unrefereed, posted in the site's thread.

2026_03_19_chojecki_conditional: A note deducing that the logarithmic density of the sifted set of Problem 25 exists, and equals the limit of the truncation densities, from an unproved uniform harmonic estimate for its first-kill quotient sieves.
