 Suppose we have three sizes of a class, T1, T2, T3 of Y's and Z's.
-Assume T1, T2, T3 occur within a contiguous string of Y's and Z's. Then you get a 4th kind of this class (within the whole scale) by using a string including an X, say XY or XZ.
+Assume T1, T2, T3 occur within a contiguous string of Y's and Z's. Then you get a 4th variant of this class (within the whole scale) by using a string of the same length including an X.
 So it's pretty obvious that you havve to have MV2 within a contiguous string, but what about the whole string minus the X's?
