Composites Among $[\xi 7^n]$ and Right-Truncatable Primes in Base 7
VibeMathed reports this item as resolved. VibeMath preserves that report as a source assertion and has not independently authored a plain-language mathematical explanation.
Precise statement
For every real $\xi>0$ the sequence of integer parts $[\xi 7^{n}]$, $n=0,1,2,\dots$, contains infinitely many composite numbers. Second, there is no infinite right truncatable prime in base 7.
This statement is indexed from an attributed source. VibeMath has not independently audited statement fidelity, correctness, priority, or novelty.
