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 table on table
• the side: two can form a sidewalk
• the bun (also known as R-bee): two can form a cis-mirrored R-bee, a trans-mirrored R-bee, a cis-rotated R-bee, a trans-rotated R-bee or a skew R-bees.
• the bookend: there are five different ways to form a still life from two of them, analogous to the bun
• 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.
