The dove (or R-mango or R-havoc) is a simple induction coil and nonoplet.

If left to evolve on its own, it stabilizes at generation 200 as a fairly sparse formation of 3 blocks and 2 blinkers.

The stairstep hexomino, if half of it is deleted after the two halves initially separate, forms a dove in 42 generations. The dove forms a lumps of muck sequence (although through a different predecessor) in what is effectively 20 generations. This is the basis of the p124 lumps of muck hassler; 2×(42+20) = 124.

Dove-dove still lifes

As mentioned previously, it can act as an induction coil. Two doves suffice to make a still life, with five possible isomers:

A sixth still life exists in which physical connection between both doves exists:

Use in conduits

The dove is a recognized conduit object, represented by the letter D.
