Following the comments of Dodd and Wojowu, the condition $p \neq 2$ has been added, since this is clearly necessary.

| Feb 7, 2021 at 22:02 | comment | added | Wojowu | By Jacobi's four square theorem, the number of solutions in $\frac{1}{5^k}\mathbb Z$, equal to the number if integer solutions to $x^2+y^2+z^2+w^2=5^{2k}$, is equal to $8(1+5+\dots+5^{2k})$, so we definitely have many solutions. This doesn't tell us how they are distributed, but at least we can't have finiteness issues like with $2$. | |
