Infinite weak Carmichael families with a fixed prime

About 13 years old · traced to

For integers e,fe,f with 1≤e≤f1\le e\le f and e+f≥3e+f\ge 3, and an odd prime qq, let Qw(q;e,f){\mathcal Q}_w(q;e,f) be the set of primes pp such that peqfp^eq^f or qepfq^ep^f is a weak Carmichael number. Infinite weak Carmichael family conjecture.

⋃1≤e≤f<∞Qw(q;e,f)\bigcup_{1\le e\le f<\infty}{\mathcal Q}_w(q;e,f)

is infinite. The claim predicts infinitely many compatible weak Carmichael constructions for each fixed odd prime qq.
