<p>Just browsing some old stuff in my office for other thing I found the following:</p>
<p>$230.$ (April, 1915) Proposed by E. B. Escott, Ann Arbor, Michigan.</p>
<p>Find three numbers such that their sum, the sum of their squares, and the sum of their cubes
, shall be a cube.</p>
<p>Note.--W. D. Cairns says this problem, which was proposed in <code>L'Intermediaire</code> in $1900$,
remains unsolved to date, even though it was reprinted in February, $1913$.</p>

Escott, Ann Arbor, MichiganTapio Rajala2011-02-09T12:14:15Z2011-02-09T12:14:15Z<p>With a quick search from the internet I was able to only find the solution $$(146, -1314, 1168)$$ by <strong>E. T. Bell</strong> in <em>The American Mathematical Monthly</em>, Vol. 24, No. 5 (May, 1917), p. 240. The paper can be found from <a href="http://www.jstor.org/stable/pdfplus/2974328.pdf" rel="nofollow">http://www.jstor.org/stable/pdfplus/2974328.pdf</a></p>
<p>(Also, a quick computer search shows that there are no positive solutions with the largest integer being less than 90000.)</p>
