Thanks, both. How about pattern 18?

Alternatively grouped kite (or turbot fish).
You didn't ask for pattern 7: empty rectangle or grouped kite again.

Not sure where u see the kite In 18?

Kites (grouped )are usully like this

Code: Select all

Ah, you are right, i saw now that Havard had called that one "fish pattern", not kite (like him i see all those patterns just as 2 strong links weakly connected).
And - oops - in #7 there is no empty rectangle ...
Anyway, Red Ed should have the most common names of today now for the 3 basic patterns (finned x-wing, grouped kite and empty rectangle).

Empty rectangle
Or franken x wing

"franken x wing" is almost correct

finned Franken X-wing

r6b9\c17
with a fin in r7c89

* r7c89

• is a fin [singular]
• are fin-cells [plural]

finned Franken X-wing

r6b9\c17
with a fin in r7c89

* r7c89

• is a fin [singular]
• are fin-cells [plural]

terminology in The Ultimate FISH Guide

Aaaagh! TUFG definitions mix the terms fin sectors and fin cells interchangeably and improperly ... and often uses the term fin for either instance. Fin sectors occur in Nx(N+k) fish usage. Fin cells occur in NxN fish usage.

finned (cells) Franken X-Wing r6b9\c17 w/fin cells r7c89

In Nx(N+k) fish terminology:

finned (sectors) Franken X-Wing r6b9\c17+r7

Here, all of the NxN fin cells and eliminations are covered by a single fin sector -- r7. Sometimes, multiple Nx(N+k) fish are needed to account for all of the eliminations in a single NxN fish.
