X-Cycles (Fishy Cycles)
Points.
An X-Cycle is a single digit continuous loop made of N truths covered with N
links, like basic fish. It therefore has a rank of 0 and eliminates all extra
candidates in any of the covering links.
X-Cycle Example 1. Three truth,
(length 6) X-Cycle made from all rows. Covering links are shaded black
indicating rank 0.
