Eric Solomon
An (m-n) solution has m regions
of one color and n of the other.
This is the only (2-2) solution
known. There is no (1-1) solution
(see proof.html), but there
may be a (1-n) solution for n>1.
Duncan Jones
A (3-3) solution.
Andrea Gilbert
Andrea has found a
solution with matched
opposing edges which
therefore tiles the plane
as indicated on the right.
Andrea Gilbert
Part of the infinite tiling.
Eric Solomon
This, and Duncan Jones's Spiral (above), have the
largest region of a single
color so far found.
Jose Ruperez
Graham Downes
An elegant antisymmetric solution
showing, or suggesting,
ten circles.
Duncan Jones
Kate Jones
An antisymmetric solution with eight regions of each colour. The most fragmented hexagram reported.
