Of course, the Hardy & Ramanujam story led to a series of pairs of cubes being combined in n ways (n=2 for 1729) being termed "Taxicab numbers". See a paper my father, the late Edwin Rosenstiel, which announed the discovery of the fourth in the series, published in The Institute of Mathematics and its Applications Bulletin July, 1991, Volume 27, pp 155-157. The other authors were John Dardis and myself (I did the computing on PCs of the era). My parents lived in Putney. The Hardy & Ramanujam story inspired the search that led to the paper.
