Inductee
An inductee is a pattern that resembles a still life: all cells have 2 or 3 neighbors and will therefore survive to the next generation. However, new cells may be born at some point along the pattern's perimeter. These must be suppressable by the addition of another component, typically a still life or another inductee, which will be known as an induction coil. Due to this, inductees frequently appear as the components of still lifes, sometimes also within the stators of some oscillators.
The smallest inductees and many others can be stabilized with a copy of itself, and they are thus simultaneously also induction coils themself.
- the pre-block: two can form an aircraft carrier
- the table: two can form a mirrored table or rotated table
- the side: two can form a sidewalk
- the bun: two can form a cis-mirrored bun, a trans-mirrored bun, a shift-mirrored bun, a cis-rotated bun or a trans-rotated bun.
- the bookend: two can form a cis-mirrored bookend, a trans-mirrored bookend, a shift-mirrored bookend, a cis-rotated bookend or a trans-rotated bookend.
- the cover: two can form a 16-cell still life (xs16_178bq2sg)
The large component of eater 2 is an example: the siamese hats are unstable without the block, and the block will not survive a glider hit without the hats.
