Karsten, your query about copying Lucas sequences from Citizendium has reminded me I haven't finished working on Lucas multiplication table (it should look much like Fibonacci multiplication table once completed). Alonso del Arte 23:27, 13 November 2010 (UTC)

Re: Links to Axxxxxx pages

Instead of using [[OEIS: A000001]] or [[OEIS: A000001|Link text]], it is better to use the template {{oeis|A000001}} (giving A000001) or {{oeis|A000001|Link text}}. — Daniel Forgues 05:25, 19 December 2010 (UTC)

1729 is the Hardy-Ramanujan number

1729 is the Hardy-Ramanujan number, the smallest number that is the sum of 2 cubes in two different ways: $\scriptstyle 1729\,=\,12^{3}+1^{3}\,=\,10^{3}+9^{3}\,$. — Daniel Forgues 05:47, 19 December 2010 (UTC)

$\scriptstyle 1729\,=\,7\cdot 13\cdot 19\,$, 19 is missing. — Daniel Forgues 05:51, 19 December 2010 (UTC)
