Alef is an induction coil with a four-cell edge. By itself, it becomes a boat, although not via a common sequence.
The cis-mirrored alef is the sixth most common still life with 24 cells. However, the simplest form, alef on block, is nowhere near the top of the list for its size; the two possible block positions rank 60th and 77th for 16-cell still lifes.
In Pedestrian Life, one of the alef on boat variants is 5,500 times as common as it is in Life, roughly in line with the hook with tail (which has relatively unchanged frequency), as it is formed from a glider hitting a B-heptomino or Herschel with the correct position and timing.
