Are we odd for liking this, too? (Posted on 2005-08-30) Difficulty: 3 of 5
In "Are we odd for liking this?" we were asked to decipher an encrypted message. Can you decipher this message too?

Some Thoughts Orthogonality | Comment 3 of 18 |

I would think that if you wanted to encode two messages in the same "space" the coding techniques should be "orthogonal".  In a perfect world you would have freedom to encode each message separately without conflicting.

The features pointed out by Avin seem to indicate that there is probably not perfect orthogonality between the "wrong" coding and the "right" coding.

I've tried looking at different subsets other than just the odd numbers.  No luck.

This seems to indicate that the solution might not be a feature of individual numbers, so I also tried looking at the "oddness" of the sum of two adjacent numbers.  No luck there either.

Still working...
