$1444$

Mistake

$1444$ is also the $4$th square whose digits form two other squares juxtaposed, $1444 = 144 : 4$.

Correction

It is actually the $5$th, after $49$, $169$, $361$ and $1225$.

This mistake is corrected in Curious and Interesting Numbers, 2nd ed. of $1997$, which explicitly lists the squares in question.
