Abstract
The Erd\H{o}s primitive set conjecture states that the sum , ranging over any primitive set of positive integers, is maximized by the set of prime numbers. Recently Laib, Derbal, and Mechik proved that the translated Erd\H{o}s conjecture for the sum is false starting at , by comparison with semiprimes. In this note we prove that such falsehood occurs already at , and show this translate is best possible for semiprimes. We also obtain results for translated sums of -almost primes with larger .
