None of us has yet managed to fathom out what's so special about 20120121122515626145776622735224615338815731191617, though we already tried hard to reveal this mystery.

I myself think it's a randomish number with a few possibly special elements, such as the large number of double digits and the string of 1s in binary.

The 216digit number which Max handwrites on paper (different from the (YOUR!) 218digit number displayed onscreen by Euclid) is: 884509627386359275033751967 943067599621731590401694134 434007629683591574337516791 197615733475195375920401694 343151239621353184932676605 800621596380716399501371459 954387507655892533875618750 354029981152863950711207613. The piece of paper he writes it on has "Only God is Perfect" at the bottom.
