[seqfan] Using the OEIS on a very hot day

[Peter Luschny]

It's really, really hot here and I am sitting with my buddy
Hans on the veranda.

Asks Hans: "Does the OEIS has any real use?"
Me: "I don't know."

After a while Hans demands: "Give me your birthday!"
He took his tablet and entered the three numbers in
the search box of the OEIS.

Hans: "Ah, did you know that these are all prime numbers?"
Me: "No, I don't care about such things."

After scrolling for a while through the many pages the
database returned Hans said:

"But these are not ordinary prime numbers. They are all
related in a peculiar way to twin primes."

Me: "Really?", reluctantly I opened my eyes. Hans indeed found
a sequence which gives a formula relating them all in the
same way to twin primes.

Moreover, assuming that they represent the components of a
date, say between 1935 and today, they uniquely identify this
date. So I could trade in the date of my birthday for the
A-number of this sequence and save 2 digits.

Hans: "Well now, do you see that the OEIS has good use?"
Me: "Hm, maybe..."

Cheers, Peter

P.S. What's about your birthday in the OEIS?
