Ancient Hindu mathematicians used the following rational approximation for the number $\sqrt{2}$:

$$
t=1+\frac{1}{3}+\frac{1}{3 \cdot 4}-\frac{1}{3 \cdot 4 \cdot 34}
$$

What is the maximum percentage error of the approximation? - How many leading digits of $t$ in decimal form match the decimal form of the approximate fraction of $\sqrt{2}$?
