Also, does this mean that my user puzzle is coming up soon? :-)


I'm guessing a bitwise nand? I haven't actually given the puzzle a go, but seeing what numbers appear in the &-cages, it seems quite likely.

I probably should have paid more attention to the use of & as the symbol for the operator. [blush]

Complete Change of Original Post: Bitwise And : One will have to use Binary, just as one does for Bitwise Or

To have a bit turn on (= 1) represented in the final answer, every number in the cage must have that bit turned on (= 1)

(6,7) & = 1
101
111
001

(2,5) & = 0
010
101
000

(3, 5, 7) & = 1
011
101
111
001

Ah, I had forgotten you submitted one like that, I'll take a look and let you know.

The next user puzzle will be another one by kus_theo, on Saturday.
