Longest constrained sequences
From Polymath Wiki
The numbers in square brackets show (what we know of) the length of the longest sequence of discrepancy 2 satisfying the given constraints exactly. The notation [math]\displaystyle{ a=b }[/math] is shorthand for [math]\displaystyle{ T_a(x) = T_b(x) }[/math], and [math]\displaystyle{ a=-b }[/math] for [math]\displaystyle{ T_a(x) = -T_b(x) }[/math].

- Asterisk means that a depth-first search with a little look-ahead showed that the maximum is finite, but the actual maximum may be slightly above that shown.
