The number 1729 is mentioned in "A mathematician's apology" by G. H. Hardy.
>From Wikipedia:
"1729 is known as the Hardy-Ramanujan number after a famous anecdote of the
British mathematician G. H. Hardy regarding a hospital visit to the Indian
mathematician Srinivasa Ramanujan. In Hardy's words:[1]
" I remember once going to see him when he was ill at Putney. I had ridden
in taxi cab number 1729 and remarked that the number seemed to me rather a
dull one, and that I hoped it was not an unfavorable omen. "No," he replied,
"it is a very interesting number; it is the smallest number expressible as
the sum of two cubes in two different ways." ""

Dear Sequence Fans, This was just submitted. Could someone clean it up (edit
it, find more terms, check if is new, etc.)?
