Methinks when looking for swordfish is a losing proposition, looking for jellyfish ain't no better. I'm happy to solve puzzles with any non-T&E moves.  |

Keith, in a recent thread you stated "I believe a regular (unfinned) fish always has a complement. "
What did you mean by "complement?"
I'm trying to find the complement swordfish (or any fish) to the one in this puzzle (3s, columns 157.) |

Normally, I wouldn't include the Starfish, but the topic of complementary fish was also included in the discussion.
[Edit: changed Whale to Starfish.]

to the one in this puzzle |
the 3 is missing 8 times,
so the complement of a Swordfish is the remaining 8-3=5 rows and columns,
i.e. a Squirmbag r12467\c23489
( which daj95376 has posted as a "Whale" ) |

By complement I mean: If there is a fish in the rows (columns), there is another complementary fish in the columns (rows) that makes the same eliminations.
In this case, there is a swordfish on 3 in C157. There is also a squirmbag on 3 in R12467 that makes the same eliminations.

| 567 3579 369 | 268 4 1 | 79 68 23 |
| 1 8 36 | 267 9 67 | 5 4 23 |

| 4 1 68 | 9 368 2 | 38 5 7 |
| 56 35 2368 | 3468 7 4568 | 1 238 9 |
+----------------+----------------+----------------+
| 9 6 1 | 378 2 78 | 4 378 5 |
| 38 2 7 | 146 5 46 | 38 9 16 |
| 38 4 5 | 1678 368 9 | 2 1678 168 |
+----------------+----------------+----------------+ |
There is a jellyfish on 8 in the rows and a complementary jellyfish on 8 in the columns.

A complementary whale/squirmbag! That's great. Obviously I was not setting my sights high enough.
My compliments on finding that. |

I changed Whale to Starfish -- an alternative to Squirmbag -- in my post above. That's what I get for working on puzzles in the middle of the night. _  _
| Code: | Size of Fish:
1. 1-Fish (aka Cyclopsfish): All elements are in 1 x 1 sector
2. X-Wing : All elements are in 2 x 2 sectors
3. Swordfish : All elements are in 3 x 3 sectors
4. Jellyfish : All elements are in 4 x 4 sectors
5. Squirmbag (aka Starfish): All elements are in 5 x 5 sectors
6. Whale : All elements are in 6 x 6 sectors
7. Leviathan : All elements are in 7 x 7 sectors

That's not hard: You know something is there, and you know which cells it eliminates.
Or, Sudoku Susser will show it to you.

i did not intend to imply that i found a Squirmbag
what i was trying to say is,
take all rows not involved in the Swordfish,
and all columns not involved in the Swordfish,
= the complement
the complement is a fish
(in the present case a Squirmbag);
it is equivalent to the original Swordfish
(equivalent -- same exclusions) |
