Mistake

 * The largest triangular number to be the product of consecutive integers. The others are $6$, $120$, $210$, $990$ and $185 \, 136$.

This should read:
 * The largest triangular number to be the product of $3$ consecutive integers. The others are $6$, $120$, $210$, $990$ and $185 \, 136$.

For example, $7140$ is a triangular number which is the product of $2$ (and not $3$) consecutive integers:
 * $7140 = T_{119} = \dfrac {119 \left({119 + 1}\right)} 2 = 84 \times 85$
