displaying each candidate 2:
2x2 2xx 2xx
xx2 xxx 22x
xx2 x2x 2xx

xxx 222 xxx
xxx xxx xxx
xxx xxx xxx

xx2 x2x 22x
xx2 xxx 22x
2x2 222 x2x
looking at rows 2,3,7 and 8 do the 2s form a 4*4 version of an x-wing in the same way that a swordfish forms a 3*3 version?
i.e. if they do the candidate 2s at r1c3, r1c7, r4c5. r9c3, r9c5, r9c8 can be eliminated?
cheers muchly

I believe the 4x4 version of a swordfish is known as a Captain Swordfish though I'm not certain. I recommend you check with tso.

I believe there is a swordfish interlinked with your 4*4 at:

r1c1,r1c4,r4c4,r4c6,r9c1,r9c4 and r9c6

This will remove the same candidates as your 4*4

2x2 -- X-wing
3x3 -- Swordfish
4x4 -- Jellyfish
5x5 -- Squirmbag

5X5 -- I'd much prefer "Quintopus"!

5X5 -- I'd much prefer "Quintopus"!

Quintopus, pentapus, starfish, ... almost anything would be better than "squirmbag" (yuck!).

[tso]

I think "Squirmbag" was coined in jest and unfortunately stuck. "Starfish" is far better -- and that's what I'll use from now on -- moot as it may be -- since I've never seen one.

Starfish (Oxford English Dictionary) - a marine echinoderm with five or more radiating arms bearing tube feet underneath [Class Asteroidea: many species.]

Starfish for >4X>4 it should be then.

Mind you naming a 5x5 is a moot point for 9x9 sudoku; it will never appear without also a 4x4 or lower. If you have a starfish by columns, you have at most a jellyfish by rows.

... and humans have 10 or more fingers.

With my keyboard "skills", it's more like ten thumbs at times!.
