wing
(5=9)r7c5-(9=8)r9c5-anq:[(8=3695)r789c3,r9c1] => -5r7c12; stte

or

(5=9)r7c5-(9=8)r9c5-(8=3695)r789c3,r9c1 => -5r7c12; stte



Does the anq:[] help? What about ALS:[]?

I think it is easier to understand without the alphabet soup.

I was expecting ...
Chain[6] : Death Blossom : (356=9)r789c3-(9=8)r9c1-(8=59)r79c5 :=> -5r7c12; UP81 Wink
Or, may be, ...
Chain[6] : ALS-XZ Rule : (3569=8)r789c3.r9c1-(8=59)r79c5 :=> -5r7c12; UP81 Very Happy

I was expecting one less strong inference ... pseudo w-wing: (5=9)als:r789c3-(9)r9c1=(9)r9c5-(9=5)r7c5

Very Happy I like it! Would this be proper?

pseudo xy-wing (5=9)r7c5-(9=8)r9c5-(8=5)als:r789c3,r9c1 => -5r7c12; stte

Interesting to see reference to a Death Blossom
Which leads to some considerations :
There is a category distinction between Patterns which result from an interesting concept, and which are detected by looking for a manifestation of the concept on a grid, and Patterns which are merely short AICs possibly with certain characteristics (look for a bivalue...).
These latter aren't generally seized in their entirety without running through the AIC : so the AIC is fairly integral.
The former patterns make no recourse to AIC logic which is in many ways their attraction.
They can of course be demonstrated by AIC logic.
No one sees a Jellyfish as an AIC, no-one demonstrates by AIC that the jellyfish is solid in its logic.
No one sees a DL-ALS as an AIC (some such might be found by AIC logic as a loop, but then we are back into that second category of pattern).

So back to Death Blossom
If the Pattern is to survive in the memory, it deserves to be presented by its conceptual logic, and not by AIC.
Taking JC Van Hay's example, this might give
Death Blossom
stem 89r9c1
ALS 3569r789c3
ALS 589r79c5
{5369} {98} {895} : =><5>r7c12

Well, leave for one day and you miss all the fun.

And besides that, I missed the als in b7 and could not find any other solution. Good job Dan. Exclamation

I may pursue the Death Blossom later but for now it has lost all of its fragrance. Wink Wink

It looks proper enough to me. For discontinuos loops, the other digits of the ALS are irrelevant. I also like your use of a comma, rather than '|', to separate list items.
