I took a hiatus to work on other codes, it’s frustrating when no one can see what you see! In the dedication to Shakespeare’s sonnets can anyone else see “To H Wriothesslie and Ben Iohnson” (you have to put the letters in a 12×12 square first)
on Kryptos I think I am at least warm on this;
Subtract the letters NYPVTTM from the number the letters are in sequence ie. 64-70 and then use an alphabet square on the results
64 65 66 67 68 69 70
N Y P V T T M
50 40 50 45 48 49 57
X N X S V W E
B E R L N I
using alphabet square;
X-Y=B
N-E=R
X-L=O
X-O=R
S-T=L
V-I=N
W-M=I
E-P=L
L-T=I
It’s not perfect, but might be close (?)
Thanks
