G. H. Hardy, the Cambridge mathematician called to see the Indian mathematician, Srinivana Ramanujan. Hardy mentioned that his cab had been numbered 1729, which he considered to be an extremely dull number. Ramanunjan was scandalised and pointed out that far from being dull, the number was expressible as the sum of two cubes in two different ways:
[123 x 123 x 123] + [13 x 13 x 13] and [103 x 103 x 103] + [93 x 93 x 93]
[123 x 123 x 123] + [13 x 13 x 13] and [103 x 103 x 103] + [93 x 93 x 93]
