@no_brainer @Gaelan @fesshole I guess it's more whether they're in the first hundred digits otherwise yes it's sort of meaningless as I am also fairly sure every combination occurs somewhere as that's part of being irrational

My phone number is a 7-digit prime that shows up in the digits of pi. My husband's phone number is a 7-digit prime that shows up in the digits of e. We met when training students for the Maths Olympiad. The fess is how nerdy we both are.
@fesshole
And when you multiply, RSA is born. -
@no_brainer @Gaelan @fesshole I'm not certain but I thought most sequences were, and 7 is a short length.
Guess you can search for your number on a page with the first million digits

@fesshole wait, isn’t it safe to assume any sequence of 7 digits will appear at some point in the digits of both pi and e?
@Gaelan you have an application for that ^^ : https://www.angio.net/pi/
(with 100 million of pi decimals, the odds seems to be 99.995%)

@fesshole whereas if you’d met at a cybersecurity convention you’d still not know each other’s numbers.

@fesshole Check your numbers here. https://www.angio.net/pi/

For the technically minded, the name for such numbers is 'normal numbers'. Not much is known about the relationship between the transcendentals and the normals, or even whether some common algebraics are normal.
So the thing about π at the end of Carl Sagan's Contact, if true, may be either profound or trivial.

@fesshole That the numbers are both prime is a cool coincidence, but all numbers show up in irrational numbers like pi and e.
@nwalfield@mastodon.social @fesshole@mastodon.social that's not true for all irrational numbers

@fesshole My phone number is a sequence of digits assigned by a mobile operator thirty years ago, when I switched a previous one. It doesn't tell anything about me, even if you can reach me with it. I'm still not enumerable. If you insist enough you could find my DNA sequence in pi or e. Again, they'll keep being coincidences.

@nwalfield @fesshole An irrational number doesn't necessarily contain any given sequence of digits in its decimal expansion. It is not known whether this is true for pi. All short sequences (like phone numbers) have probably been found, though.

The interesting question is whether it actually is stricter. It would certainly seem so on its face. But I don't know whether it is conjecture or proven that there's a difference; and I have long since learned to be wary about making claims about infinitely big things based upon intuition alone. (-:

@fesshole All prime numbers show up in those digits, no? 🙂

@fesshole you can choose your phone number?

@nwalfield @fesshole actually no. An irrational number whose expansion includes all possible integers as subsequence is called a normal number, not all irrational numbers are normal; in fact, not even all transcendental numbers are normal. In fact (bis), pi and e are only CONJECTURED to be normal. No proof of their normality has ever been given.
