A sequel to The Numberphile Heist (part 1)

You hear a click, and a slight push reveals the entrance. Looking at what's inside, you laughed at your own naïvety.

Instead of a mountain of brown paper, you're faced with merely another vault. On the door is a QWERTY keypad, and a plaque:


Gosh darnit, Brady protects his brown paper well. Unfazed, you try to figure out what the code could be.

  • $\begingroup$ @micsthepick HAHAHA I absolutely love your attitude! This puzzle is nowhere near as complicated as my other ones! More important should be who this plaque is commemorating, and what those two people mean :) $\endgroup$

1 Answer 1


I am going to go out on a limb and guess that the password is something involving the word sum or summation.

Goldbach created Goldbachs conjecture which states that "Every even integer greater than 2 can be expressed as the sum of two primes"

Durer was an artist who famously featured a magic square in one of his prints. A magic square is a grid of numbers where the sum of the numbers in any horizontal, vertical, or main diagonal line is always the same number.

The thing these two have in common involves summing numbers.
