Swordfish Pattern. This
Swordfish pattern has 3 truths covered by three links as opposed to an X-Wing
with 2 truths and 2 links. The logical reasoning is the same as the X-Wing,
if all the candidates in 3 truths are contained in 3 links, then no other
candidates in the links can be true, and can be removed.
