I would like to thank you for transmitting a solution by Peter Gilbert
for the iterated sum of digits of divisors problem from  Abacus
magazine.  I would like also to note that the Summer 1984 edition
of this magazine (vol 1, no 4) which I have just received contains
a discussion of some of the problems from the Fall, 1983 and Winter,
1984 issues, but there is no discussion of this problem.  Perhaps
you would like to send this proof to the problem editor:

          Richard V. Andree
          University of Oklahoma

(I don't see a more exact address for Andree).
