| Sep 16, 2021 at 22:35 | comment | added | Peter Taylor | @MattF., e.g. $a(\tfrac{4^9-1}{3}) = [(p + q)(p + pq + q^2)(p + pq + pq^2 + q^3)(p + pq + pq^2 + pq^3 + q^4)]^3$. There's a fairly clear pattern and it should be a reasonably straightforward proof by induction. | |
| Sep 16, 2021 at 22:28 | comment | added | user44143 | Will you provide a good example of such a sequence, and the corresponding cube roots for $n=2,3,4$? For what values of $p,q,n$ have you verified this conjecture? | |
