$145$

Mistake

The $5$th number to be the sum of $2$ squares in $2$ different ways:

$145 = 12^2 + 1^2 = 8^2 + 9^2$

It is in fact the $6$th after $50$, $65$, $85$, $125$, $130$.

Curious and Interesting Numbers has it as the $4$th such number. This is clearly an incorrect correction.

$\blacksquare$
