541456 and 51456. I checked 20 numbers 2000 times and found 200 patterns!!

IMO, it's a little sad how many don't understand that correlation does not (always) mean causation.

Similarly, many don't recognize when the empirical data strongly supports a causation linkage....

You might want to check that again. Neither 7 nor 73 divides their difference.

pg(43*5) is prime. 5 (odd) is congruent to -8 mod 13. pg(43*1620) is prime. 1620 (even) is congruent to 8 mod 13. pg(43*2140) is prime. 2140 (even) is congruent to 8 mod 13. pg(43*12592) is prime. 12592 (even) is congruent to 8 mod 13. pg(67*1) is prime. 1 is congruent to 1 mod 13. pg(67*768) is prime. 768 is congruent to 1 mod 13.


pg(43k) and pg(67k) are probable primes when k has a particular congruence modulo 13.

This is a great place to use the information you no doubt already learned from reading the page on multiple comparisons that has been suggested twice on this thread (now thrice). To show that you have understood, what p-value do you compute before and after Bonferroni correction? (This is just the simplest correction you could use; feel free to use a more advanced method.)

This is your chance to show that the pattern really is significant!

...pg(139*546) is prime. pg(139*24) is prime...546 and 24 are both congruent to 24 mod 29

[enzocreti]

and i think there are other coincidences

Statements of the form "x & y are congruent to k mod p" is utterly meaningless.

Pick any two number x & y.

Factorize x-y. Let p be a prime that divides x-y

x-y == 0 (mod p)
or x == y (mod p)

546-24 = 2*3^2*29

So of course they are both in the same congruent class (mod 29) (and mod 9 and mod 2)

pg(36) is prime pg(36*1935) is prime...36+36*1935=264^2!

Au contraire,
546*139 and 24*139 are both 1 mod 29
