Query: Discrete Spacings   Consider a string of $n$ positions, i.e. a discrete string of length $n$.
Units of length $k$ are placed at random on this string in such a way that they
do not overlap, and as often as possible, i.e. until all spacings between
neighboring units have length less than $k$. When centered and scaled by
$n^{-1/2}$ the resulting numbers of spacings of length $1, 2,..., k-1$ have
simultaneously a limiting normal distribution as $n\to\infty$. This is proved
by the classical method of moments.
