Sigh.... drunk and grumpy on christmas, and you have me redo the entire score board..... thanks!   ;D

 

Wait.. time out @Green Baron.

How does 10 times the sum of any two integers result in a number that isn't a multiple of 10???

40 + 33^2 = 40 + 1089 = 1129 (Pemdas, it took me a little too)

Ahhh.... sorry about that. You're welcome maybe?

 

(ignore the obviously not prime 462 part)

Only one of those is multiplied, the other is not.

Just an odd neat array of square numbers I guess.

 

Anyway :

Looks like a special case of Fermat's theorem, but my math knowledge is limited to what i need to successfully go shopping

Well, keep going, i dont wanna get so rude here.

Had to store that ace in the hole (Mersenne-13 or 8191), kinda glad @Gargamel give me that key.

1229

the last Mersenne number before 8191 is 127 (which is skipped), that's such an immense gap !!!

Gotta love wikipedia.

While looking for images, I found pictures of this bridge in Spain. It was built in 1283:
