The shillelagh siamese snake is a 12-cell still life.
Construction
The cheapest known way of constructing this still life uses 5 gliders.[1] A 5-glider synthesis was found in February 2023.[2] Several known syntheses can be found in Mark Niemiec's database.[3]

Occurrence
Among the 121 still lifes with 12 cells, this is the 50th most common still life according to Catagolue.
There are no collisions in octohash, octo3obj or octo3g databases with this still life occurring in the ash.
