trailThe Fourier coefficients of the Syracuse random variable mod 3^n at frequencies not divisible by 3 decay faster than any power of n.
The Syracuse random variables mod 3^n are equidistributed at fine 3-adic scales, with total variation error decaying faster than any power of the scale exponent m.
