Title: Ultraflat real Littlewood polynomials.

Abstract: For every ${}varepsilon{}in(0,1)$ and every sufficiently large integer N, there is a polynomial of length N with coefficients in ${}{-1,1{}}$ whose modulus lies between $(1-{}varepsilon){}sqrt N$ and $(1+{}varepsilon){}sqrt N$ everywhere on the unit circle. Thus real Littlewood polynomials can be ultraflat through every sufficiently large integer length. The signs may be chosen separately at each length.

This abstract is a catalogue record. It is not a verification and not a premise. It does not close O.1. O.1 stays NOT_CLOSED. No quantum coefficient is admitted. No compilation is asserted.
