Some play with the primes and thinking of graphic cards

7 is "flat circle"

1+2+3 = 6^1 = 5 + 1 =0 + 2*3 

13+17+19 = 49 = 7^2 + 0
167+173+179 = 519 = 8^3 + 7 ( circles 512-bit ) = 0 + 173*3 

2161+2179+2203 = 6543 = 6561 - 6*3 = 3^8 - 6*3; 6561= 2187*3= 729*3*3 = 243*3*3*3 = ... = 3^8

... 10^5=100 000

at Assembler language: 0, 173... in Depth 

7-bit additional register for circle amedments !!!

I think it's not done, Example: GeForce GTX 285
