My problem is this:

I have 12 values, one for each month of the year.

With in a worksheet (IE no VBA) I need to estalish whether any 3
adjacent values are identical.

IE

J F M A M J J A S O N D
1 2 2 2 4 4 3 6 2 4 6 3

IN this example the answer is "Yes" there does exist a situation where
3 adjacent values are identical.

Any clues please? It's tricky to find a function or combination of
functions that wou;d it.
