Hmmm... it appears to generate correct results... here is the relevant
passage from the research paper:
[C]VCVC ... [V]
where the square brackets denote arbitrary presence of their contents.
Using (VC){m} to denote VC repeated m times, this may again be written
as
[C](VC){m}[V].
m will be called the measure of any word or word part when represented in
this form. The case m=0 covers the null word. Here are some examples:
m=0 TR, EE, TREE, Y, BY.
m=1 TROUBLE, OATS, TREES, IVY.
m=2 TROUBLES, PRIVATE, OATEN, ORRERY.
The rule you've written returns the correct m for these words, as well
as anything I've thrown at it so far.
Thanks
