Non-trivial solution to $\sum^{n}_{i=1}\sum^{n}_{j=1,j\ne i}(x_{i})^{(x_j)}=(\sum^{n}_{i=1}x...
This problem was first asked at Mathematics Stack Exchange, where it wasn't drawn much attention.
For ease of reading,
$$S=\sum_{i=1}^nx_i, S_p=\sum_{i=1,i\ne p}^nx_i, S^{[q]}=\sum_{i=1}^nx_i^q, S_p^{ …

The results are shown in this answer.
The upper bound of $S^{S_n}$.
I proved that $S^{S_n}\le n(n-1)$.
@mathlove commented that $S^{S_n}\le n(n-1)/2$.
I proved that $S^{S_n}\le\frac{n^2-3n-6}2$.
The …
