Default Prime After Prime

Here is a song called "Prime After Prime". It is a way to recall the first 15 prime numbers. It is sung to the tune of "Time After Time" by Cyndi Lauper.

2, 3, 5, 7, 11, and 13.
Prime after prime.
17, 19, and 23.
Prime after prime.
29, 31, and 37.
Prime after prime.
41, 43, and 47.
Prime after prime.

.
A character in the new Apple+ TV series Foundation a young character named Gaal Dornick recites primes to regain composure and achieve inner peace..

She goes like this. 819,250,973 ... 819,250,997 ... 819,251,011 ...

A couple of minutes or so she goes. 819,751,043 ... 819,751,061 ... 819,751,099 ...


Yes, I checked. They are indeed consecutive primes....

That is the information I never needed to know, but I appreciate it now that I know it.

The first four corresponding Mersennes have known factors; the last two are NF to 73 bits each.
Overall that's consistent with finding factors for ~2/3 as usual.

M819751061 and M819751061 now TF NF to 84 bits, and P-1 NF to sufficient bounds.

I don't see a mnemonic benefit, nor the need for one. (Do the digits map to the musical notes somehow?) Mentally sieving such small values is fast and more reliable than memorization.

If you want to create a song (even if it is Girl You know it’s True by Mili Vanilli) that serves as a mnemonic for the first 15 mersenne exponents be my guest. Check https://oeis.org/A000043

For the first 15 primes. (known since the at least the 7th century BC) I suggest this.

number 2
plus the next 14 odd numbers that
are not divided by 3 and/or 5 https://oeis.org/A000040
