The heavyweight spaceship (commonly abbreviated to HWSS) or (rarely) big fish is the fourth most common spaceship after the glider, lightweight spaceship and middleweight spaceship. It was found by John Conway in 1970 and travels at a speed of c/2 orthogonally. Its domino spark can be used to stabilize several tagalongs, including sidecar and half of x66. It is one of only three known spaceships that is a polyomino in any of its phases.
Commonness
The HWSS is the thirty-fifth most common object on Adam P. Goucher's Catagolue.[1]
