  Hjorth proved from $ZF + AD + DC$ that there is no sequence of distinct
$\Sigma^1_2$ sets of length $\delta^1_2$. Sargsyan extended Hjorth's technique
to show there is no sequence of distinct $\Sigma^1_{2n}$ sets of length
$\delta^1_{2n}$. Sargsyan conjectured an analogous property is true for any
regular Suslin pointclass in $L(R)$ -- i.e. if $\kappa$ is a regular Suslin
cardinal in $L(R)$, then there is no sequence of distinct $\kappa$-Suslin sets
of length $\kappa^+$ in $L(R)$. We prove this in the case that the pointclass
$S(\kappa)$ is inductive-like.
