Abstract When
$kgeqslant 4$
and
$0leqslant dleqslant (k-2)/4$
, we consider the system of Diophantine equations
egin{align*}x_1^j+ldots +x_k^j=y_1^j+ldots +y_k^jquad (1leqslant jleqslant k,, j
e k-d).end{align*}
We show that in this cousin of a Vinogradov system, there is a paucity of non-diagonal positive integral solutions. Our quantitative estimates are particularly sharp when
$d=o!left(k^{1/4}
ight)$
.
