Barge with long tail is an 11-cell strict still life.

This still life is comprised of the normally stable barge with a normally unstable long tail attached.

It can be substitutively referred to as the shillelagh with barge, with the pre-block of the shillelagh replaced with a barge, however "barge with long tail" is usually preferred for this object.

Occurrence

See also: List of common still lifes, Most common objects on Catagolue

It is the 32nd most common (i.e. 15th rarest) 11-cell still life out of 46. It is 60 times as rare as the 9-cell tub with long tail, 80 times as rare as the 10-cell boat with long tail, and 1.5 times as common as the 12-cell long boat with long tail.

This still life does not occur in final patterns of collisions in octohash, octo3obj or octo3g databases.

Glider synthesis

Main article: Glider synthesis

This still life is known to be constructible with 5 gliders.[1] Several known syntheses can be found in Mark Niemiec's database.[2] A 5-glider synthesis was found and submitted to Catagolue by Carson Cheng[3] in April 2022.[4]
