Also applies to 1089:

Goldtiger997 wrote:Let pₙ denote the nth prime.
Prove that for all real h > 1, there are infinitely many integers n such that pₙ < nʰ.
Suppose that there are only finitely many integers n such that pₙ < nʰ, that is to say, there is a largest integer m such that pₘ < mʰ.
Thus the
sum of the reciprocals of the primes can be written as
1/p₁+1/p₂+1/p₃+...+1/pₘ+(1/pₘ₊₁/pₘ₊₂+...)
which is less than
1/p₁+1/p₂+1/p₃+...+1/pₘ+(1/Mʰ+1/(M+1)ʰ+...)
which converges if h > 1.
But the sum of the reciprocals of the primes diverges. Contradiction.

He/she probably meant "my only great-grandmother who is still alive".

CGoL mathematics: the number of unique snake-carrier chain still lifes with 6+4N cells (N≥0) =
OEIS A005578(N+2).
e.g. for N=1 there are three examples:
Code: Select all
x = 27, y = 4, rule = B3/S23
2ob2obo3b2ob2o5b2o$ob2ob2o3bob2o2bo3bo2b2o$15b2o5b2o2bo$25b2o!
EDIT: BlinkerSpawn pointed out on the Discord that I made an arithmetic error; the correct formula is actually
A001405(N+2).
EDIT 2: Nope, that was also wrong, it's
A005418(N+2).

Nice, that's basically the same method as mine.

Sorry, I wasn't very clear. I was aware of that pattern, but what I was wondering about was the distribution of families in different bases.

Wow, this is my 500th post. I didn't realize it would happen so quickly.
I manage the
5S project, which collects all known spaceship speeds in Isotropic Non-totalistic rules. I also wrote
EPE, a tool for searching in the INT rulespace.
Things to work on:
- Find (7,1)c/8 and 9c/10 ships in non-B0 INT.
- EPE improvements.

I believe I did three different things. Which one were you referring to?
Edit: Edit 3: actually I will stop avoiding another post by editing.
Edit 2: just realised this was my 365th post; one for everyday of the year.
