A215889: Decimal expansion of

3√  1729

.

{ 12.0023143684... }

In his poem for Richard P. Feynman, Elliot Wolf gives this number as “12.002314 to be precise.” This number is of course irrational. 1729 is the Hardy-Ramanujan number, the smallest positive integer which is the sum of two cubes in two different ways, 9 3 + 10 3 = 1 3 + 12 3. Thus, 1729 is a quasi-cube (i.e. it exceeds a cube by 1).
