by expanding the bivalve cell from a size 1 als =>
into an als consisting of N cells holding N+1 digits we can move this technique up to higher power.
simplistic examples: as this technique as an als has way to many examples to nail them all down
formations for the strong links featured in m-wing thread remains the same.
the eliminations process is a bit more technical:
peers of Als cells holding "B" candidate and peers of the "B" end point cells can be eliminated for "B"
- Code: Select all

. abc . | bc . . | . -b . . ab . | bc a . | . -b .
. . . | . . . | . . . . . . | . / . | . . .

Ring variations become a bit more technical:
the "b" link must be peers of all b cells in the Als .
then eliminate {z} all non [a,b] candidates in als A from any peer cells of all [z] cells in als A.
plus the regular w-ring eliminations caused by the loop.
- Code: Select all
example: Als - M - Ring
