Euler on trial (Posted on 2015-05-14)

Euler proposed that the equation a⁴+b⁴+c⁴ =d⁴ had no solutions in integers (excluding the trivial 0,0,0 of course).

Nowadays, is it true or not?

Per that same paper, the smallest solution is:

95800^4 + 217519^4 + 414560^4 = 422481^4

This is the only solution where all terms are co-prime and under a billion.

The only other solution under a billion is achieved by doubling each of the terms.
