Is the error to assume that any logic at all might apply to this matter? "Whereof one cannot speak, thereof one must be silent."

On the other hand, if more innocent people lacked the awareness to avoid dodgy areas then they probably wouldn't be so dodgy!

Yes split_ifs is in Mathlib so I have replaced it with split (twice) which is in Core. I believe there is also an intermediate level Std. I'm not sure why you'd want to avoid Mathlib but I daresay it's possible for many types

They iterate f where f(z) = (a₀ + a₁ z ź + a₂ Re(zⁿ) + a₃ i) z + a₄ źⁿ⁻¹. You can easily check that f(z exp(i 2 π / n)) = exp(i 2 π / n) f(z).

All of these are aperiodic; it says as much in the first paragraph. Are you talking about the rotational symmetry?

This seems about right. Work with pennies why not. My very basic test suggests that 1 - 2^(-53) is distinct from 1 in double-land. So if x is the total number of pennies and 2^(-53) * x < 0.5 I can't see why any problem would arise.

The word "original" does not appear so I don't know why you've put it in quotes. Indeed you don't have to read very far down the article to find acknowledgement that something similar had been done centuries earlier
