Consider the diophantine equation where all variables are positive and distinct :

$$ X^6 + Y^6 + Z^6 = A^6 + B^6 + C^6 = I^6 + J^6 + K^6 = T $$

And $T$ is not of the form $V W^6$ for $W>1$.

What is the smallest solution ?

Are there any solutions ?

Does the existance of a solution imply that there are infinitely many solutions ?

    $\begingroup$ So you're looking for integers that can be written as the sum of 3 powers of 6 in 3 different ways with the conidition that the integer doesn't contain a power of six itself. $\endgroup$ – Ali Caglayan Dec 26 '17 at 12:27

    $\begingroup$ Basically you are looking for generalised taxicab numbers $\mathrm{Taxicab}(6, 3, 3)$ for which no solutions have been found here and thats within a radius of 17,871. $\endgroup$ – Ali Caglayan Dec 26 '17 at 12:43

    $\begingroup$ It seems to me that it is very unlikely that you will find a solution to this question, given that we know so little about generalised taxicab numbers. $\endgroup$ – Ali Caglayan Dec 26 '17 at 12:45
