Lean formalization accompanying the paper An Exponent of 1.043 for the Unit Distance Problem by Eric Naslund (cited under sources), which proves the exponent 1.043171 unconditionally with a computer-assisted certificate. Conditional theorem on unit distances in the Euclidean plane. Let B = Q(sqrt 241) and let E be the number field of degree 512 generated over Q by sqrt 241 and square roots of the eight elements -1, -71011068 + 4574225 sqrt 241, (-6101 - 393 sqrt 241)/2, (6101 - 393 sqrt 241)/2, 31 - 2 sqrt 241, 31 + 2 sqrt 241, 326 - 21 sqrt 241 and 326 + 21 sqrt 241 of B (a basis of the…
