Probabilities for Context

nOnce we have found our long Òprime code wordÓ (of say 6 to 8 letters) to be displayed, what size code words can we expect to find in its vicinity?

¨If we have a context of 700 letters, then our typical cluster words will have 4 letters or less.

¨ If our
context is 1400 letters, then the chance of any particular combination appearing will be four times larger.

nIn general, we can find the minimum text length in which to expect to commonly find words of length n by solving our equation for T with N=1, A=22 .
