New c/4 Diagonal Tubstretcher

27P4H1V1A2.1 Nicolay Beluchenko has noticed that a previously known spaceship can be converted into a small Tubstretcher. As shown at left, the four blue bits convert the ship into the smallest known puffer of any variety.

74P4H1V1A2.1 This puffer can be combined with a Tub burning fuse, found by Harmut Holzwart, to create spaceships of any length. The smallest, at 74 bits, is shown here. (The Tub fuse is hilighted in blue.)
