now if you look at the three primes and put on top of each other1,2,3-you will end up with a three-digit box.step2-add5 to this box to get box2. now add code tobox1 and this becomes box3-code:key:
0=5,1=9,2=8,3=7,4=6. now for box4,5,6.take box1 invert numbers. i twik- middle3 row and always enter it backwards to get best results. now take box two invert box2 which is the plus 5 box to get the next box. these last two steps become box4,5. now last step invert the code box-box3. this will give you the final box6.
