I agree that the collection of all nothing-up-my-sleeve numbers anyone has ever used gives you a good starting point to find a 1&#x2F;10000 curve flaw, but I&#x27;m not advocating for allowing cos(1), sqrt(2), 1&#x2F;pi, &amp;c. I&#x27;m saying: &quot;use the leading digits of pi, or the first N digits that pass some security function if you need to be picky&quot;.
