Among the 121 still lifes with 12 cells, this is the 57th most common still life according to Catagolue.
There are no occurrences of this still life in final patterns of collisions in octohash, octo3obj or octo3g databases.
Isomers
This still life is comprised of a normally stable boat and a normally unstable hook connected by a line. This is one of two possible isomers, named trans due to the corner part of the boat facing outwards from the line; the other isomer, cis-boat trans-line hook, has this corner part tucked inwards.
The closely related pattern "boat cis-line hook" is an induction coil, in much the same way as the integral is a still life whereas the house is an induction coil. Note that there is only one valid isomer for the cis-line arrangement, analogous to cis-boat trans-line hook, as the trans- arrangement would cause unwanted birth between the boat and hook.
