Hi rjamil! Your solution is fine. Just a couple of minor presentation details:

rjamil wrote:2. XY-Wings (Row-Column wise) Transport:

Might I suggest that you dropped the 's' from XY-Wings and similar wing-patterns such as WXYZ-Wings when you only mean one instance of such a pattern? I understand that it might seem logical to see two wings and thus call the pattern (VW)XY(Z)-Wings, but it's not the standard name and might cause confusion (because it makes the reader expect more than one instance). I'm guessing it's not a typo because you seem to use it consistently.

Also, please add a bit more space between the columns in the diagrams. Otherwise they're kind of hard to read. Thanks!

ER[(6)r4c9=r5c8-r5c2=#=(6)r8c2] = (6-7)r7c2 = (76)r79c8 => -6 r8c9; stte

I was wondering if it could be fishified like this:

Kraken Mutant X-Wing (2x3 + 1 fin):

[(6)c2b6\r58c9] = (6-7)r7c2 = (76)r79c8 => -6 r8c9; stte
