Just a simple question. In Angus Johnson's Help File Explanation of the SwordFish Pattern he shows that the Example also has a reciprocal Swordfish pattern.
Question: Do all SwordFish Patterns have a Reciprocal Pattern.?

All fish have a complementary fish, possibly of the same size, usually of a different size. Of course, if you haven't already solved all possible singles the complementary fish could be a 1-fish, which isn't really a fish at all.
