Abstract: A search for the integral solutions of the Diophantine equation $ {x^3} + {y^3} + 2{z^3} = k$ for $ \vert x\vert$ $ \vert y\vert$ and $ \vert z\vert < {10^5}$ was made on an I.B.M. 1620 Model 1. These results showed that there are now just 19 values of $ k$ in the range $ 1 \leqq k \leqq 999$ for which no solution is known.
