The blonk-tie (also known as block-tie-blinker or J) is a somewhat common methuselah.


The blonk-tie has four related six-cell parents.

It also has an edgeshootable eight-cell grandparent that it forms from occasionally. This utilizes a seven-cell parent of the blonk-tie.

A fishhook can each serve as a one-glider seed for a blonk-tie. In addition, a blinker can serve as a one-glider seed for its child.

the ash of a blonk-tie, including two escaping gliders

The first surviving objects created are a glider at generation 153 and a block and beehive near each other at generations 159 and 161 respectively. At generation 147, an R grandchild is creating that spawns a B-sequence. Of the two gliders emitted by the resulting Herschel, one crashes into the chaos behind, briefly creating a honey farm predecessor, while the other escapes. The chaos almost dies around generation 340 but resurges due to the formation of a wing sequence. An elevener is almost created at generation 429, and a fleet is formed at generation 503. At generation 548, the last object, a block is formed, and one generation later, the chaos is nothing but a collection of one-bit, two-bit, and three-bit sparks that are all dead two generations later.


The blonk-tie is used in several conduits. For example, when one of its parents hits a block, the collision turns into an R-pentomino that a snake-type catalyst can turn into a Herschel output and a block in the same position, just like Conduit 1.

(Like in Conduit 1, R49, and L122), another transparent block and a fishhook can be used to get an I output instead.
