Abstract: Abstract At first sight the number 1978 may not seem to be very interesting. It appears to lack the star quality of its more glamorous neighbour 1729, for example, which (as everyone knows, thanks to the celebrated story of Hardy’s visit to the sick Ramanujan in a taxi with that number) is the smallest natural number representable as the sum of two cubes in two different ways: 1729=103 + 93 = 123 + 13.
