Generalized infinitude conjecture for weak Carmichael numbers

About 13 years old · traced to

Let s≥2s\ge 2 be an integer, and let (e1,e2,…,es)(e_1,e_2,\ldots,e_s) be a fixed tuple with e1≥e2≥⋯≥es≥1e_1\ge e_2\ge\cdots\ge e_s\ge 1 and ∑i=1sei≥3\sum_{i=1}^s e_i\ge 3. Generalized weak Carmichael infinitude conjecture. There are infinitely many weak Carmichael numbers

n=p1e1p2e2⋯pses,n=p_1^{e_1}p_2^{e_2}\cdots p_s^{e_s},

where p1,p2,…,psp_1,p_2,\ldots,p_s are distinct odd primes. This generalizes the conjectured infinitude of the two-prime families.
