The Java BigInteger class has a method .isProbablePrime(int certainty) which claims to return true if a given number is likely prime up to the requested level of certainty.

I tested Elon's prime up to a certainty of 10,240, and it returned true.

This means that there is less than one chance in 10^3000 that the number is composite.

From the JavaDoc:

Returns true if this BigInteger is probably prime, false if it's definitely composite. If certainty is ≤ 0, true is returned.

Params:

certainty – a measure of the uncertainty that the caller is willing to tolerate: if the call returns true the probability that this BigInteger is prime exceeds (1 - (1/2) ^ certainty). The execution time of this method is proportional to the value of this parameter.

Returns: true if this BigInteger is probably prime, false if it's definitely composite.

Here's the Java code (String taken from above C++ code. Thanks!)

package misc.primes;

import java.math.*;

public class XPrime { static final String xPrimeString = "111111111111111111111111111111111111111111111111111111111111" + //line 01 "111111111111111111111111111111111111111111111111111111111111" + //line 02 "111111111111111111111111111111111111111111111111111111111111" + //line 03 "111111111111111111111111111111111111111111111111111111111111" + //line 04 "111111111111111111111111111111111111111111111111111111111111" + //line 05 "111111111111111111111111111111111111111111111111111111111111" + //line 06 "111111111111188888888888111111111111111111888811111111111111" + //line 07 "111111111111118888888888881111111111111188888111111111111111" + //line 08 "111111111111111888811118888111111111118888811111111111111111" + //line 09 "111111111111111118888111888811111111188881111111111111117111" + //line 10 // originally ends 7111 "111111111111111111888811188888111118888811111111111111111111" + //line 11 "111111111111111111188888111888811888881111111111111111111111" + //line 12 "111111111111111111111888811188888888111111111111111111111111" + //line 13 "111111111111111111111188881118888811111111111111111111111111" + //line 14 "111111111111111111111118888811188881111111111111111111111111" + //line 15 "111111111111111111111111188881118888811111111111111111111111" + //line 16 "111111111111111111111111188888811188881111111111111111111111" + //line 17 "111111111111111111111118888888881118888111111111111111111111" + //line 18 "111111111111111111111888881118888111888881111111111111111111" + //line 19 "111111111111111111118888111111888881118888111111111111111111" + //line 20 "111111111111111111888881111111118888111888811111111111111111" + //line 21 "111111111111111188888111111111111888811118888111111111111111" + //line 22 "111111111111118888811111111111111188888888888811111111111111" + //line 23 "111111111111188881111111111111111111888888888881111111111111" + //line 24 "111111111111111111111111111111111111111111111111111111111111" + //line 25 "111111111111111111111111111111111111111111111111111111111111" + //line 26 "111111111111111111111111111111111111111111111111111111111111" + //line 27 "111111111111111111111111111111111111111111111111111111111111" + //line 28 "111111111111111111111111111111111111111111111111111111111111" + //line 29 "111111111111111111111111111111111111111111111111111111111111";

I was able to decode the full message, "END IS NEAR" from Trump's tweet of his mug shot as follows:

The first 2 words are easy:

  • E - Election

  • N - Never

  • D - Donald

  • I - Interference

  • S - Surrender

The last word is a little more complicated.

Starting from the 'S' of "IS", Skipping forward by "5" to get each next letter yields 'N', 'E', 'A', 'R'. (i.e., skip over "4" to get to each subsequent letter).

The only extra trick is that between the 'N' and the 'E' there is only a single letter 'D'. However D == 4 (4th letter of alphabet), so we are still skipping '4' to get to the next letter.

See crude image above to confirm.

I'm not saying this was definitely intended, but I do find it interesting.

If we look at Q post 4444 we see, "second COVID-19 wave?", which is currently topical.

Or if we interpret the skipping as 5555 and search Posts for 55:55 we get exactly 2 posts:

Post #2938, which was posted at March 3rd, 2019, 2:55:55. This post contains an overview of the situation we are in.

The 2nd post is #55, which is the famous:

Look to Twitter: Exactly this: "My fellow Americans, the Storm is upon us......." God bless.

It says that this is from a population that is 80% vaccinated, so anything below 80% of hospitalizations being from that group shows the vaccine as being at least somewhat effective.

So these stats, if true, support the narrative that the vaccine has some benefit in reducing COVID hospitalizations.

Say there are 10,000 people, 8,000 vaccinated and 2,000 unvaccinated.

Suppose then 100 people end up hospitalized, 60 vaccinated, and 40 unvaccinated.

Then the hospitalization rate for the vaccinated is 0.0075 (1 out of 133.3), and the rate for unvaccinated is 0.02 (1 out of 50).

Of course it could all be lies, but that’s a different problem!

That’s the mean, not the average.

For example, the average of 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 100 is 77.5. Almost 90% of the values are well below the average.

The mean however is 6 so 1/2 the values are below and 1/2 above.
