either of its neighbors must be divisible by 6. It need not be divisible by 30 or any higher primorial. GeoffreyT2000 (talk) 22:46, 31 May 2015 (UTC)...

Euclid's proof of an infinitude of primes in fact does not use primorial primes, just primorials (which themselves are always composite after 2). — Preceding...

unsophisticated method of deterministic primality testing involving the primorials, though I have no idea whether it is "fast". It accomodates any and all...

(UTC) The integer bases where patterns would be most obvious would be the primorials (e.g. 6, 30, 210, etc.). You would notice, for instance, that in base...

measurment, instead of pure mathematics? Also as it's a multiple of a primorial it means it's one of the best at representing fractions, especially as...

prime numbers makes them unnotable enough to be not worth mentioning. The primorials might be marginally more notable in that regard but it's nothing I'd push...

But this naming scheme is not always used. For example, a primorial prime is not a primorial number which is prime, a factorial prime is not a factorial...
