The number $137$ is a prime number One of the permutation of $137$ is $173$, which is a prime number The summation of $137$ digits is $11$ which is again a prime number! My question: Is there a name for this type of numbers? There are some other Properties for $137$ in Wikipedia I found another Properties such that $137=2^7+2^3+1$ or the only

The cutoff is half way between two neighboring numbers you can round to When rounding to the nearest $5$ you could round to $135$ or to $140$ The point half way between is $\frac 12(135+140)=137 5$ Any number less than $137 5$ (and greater than $132 5$) should be rounded to $135$ This is general

The dimension that contributes to the length of the total fence is the quantity $137~\text{mm}$ That's because the planks are usually set up so that $\text{height}>\text{width}>\text{depth}$ Furthermore, I believe that the price of a single plank is based on the largest cross-sectional area of a single plank, that is $0 137~\text{m}\times 5

Therefore, $\frac{960}7$ is the the ratio of the manual time and the automated time, and hence the automated time is $\frac{960}7$ times faster, or approximately $137$ times faster To express this into a percent, note that $100$% faster means double the speed, $200$% faster means triple the speed, and so on
