            this was a very interesting puzzle tackled by the genius
Srinivasa Ramanujan.        In the year 1914, P.C. Mahalanobis, a Kings
college student in England, got hold of a puzzle from the Strand
magazine.

thanks!
 >>>    So the solutions to the Strand puzzle can be found from the continued fraction of \sqrt{2}, which  _is_  satisfying simple.
 >>>   Using Mathematica to look at the first 10 convergents
---------- is this (also) easy to do using Lisp or Python???
