    Proposed by Edward T. H. Wang, Wilfrid Laurier University, Waterloo,
    Ontario, Canada.
    
    Observe that the binomial coefficient C(10,k) is divisible by k+1 for k
    = 0, 1, ..., 9.  Characterize all natural numbers n with the property
    that k+1 divides C(n,k) for all k = 0, 1, ..., n-1.
