Is there a name for numbers whose only factors are primes and semiprimes but may not be primes in themselves? (lemmy.world)

And for how long can this pattern continue?

How long can this pattern continue? My guess is forever, since you can just multiply a prime by the next prime (2x3=6), then take that prime, and multiply it by the next (3x5=15) and so on. So it seems to me like there's an infinite number of these kinds of primes, unless I'm not understanding you correctly.

I guess they mean a naming pattern: like hemi-demi-semi-primes

(That's how we do it in music, over on my side of the 'pond': but we get to hemi-demi-semi-quavers then (afaik) give up because no one cares for more!)
