Lobster is a c/7 diagonal spaceship that was discovered by Matthias Merzenich on August 19, 2011.[1] It was the first c/7 diagonal spaceship to be found. It consists of two gliders pulling a tagalong-like object that then rephases them. It can be infinitely extended, with its wings used as pushalongs[2][3] It can also burn through one or two rows of blocks.

Lobster was voted Pattern of the Year for 2011 on the ConwayLife.com forums, tied with the fully universal Turing machine.[4]

Tagalongs

On April 12, 2025, iNoMed found a tagalong for the lobster based on a partial by Shuich01.[6]

x = 33, y = 26, rule = B3/S23 19b3o$19bo$20bo2b2o$23b2o$19b2o$20b2o$19bo2bo2$21bo2bo$21bo3bo$22b3obo $27bo$7b2o2bobo13bo$7bobob2o13bo$7bo4bo2b2o13b2o$13bo3bo6b2o2b2o2bo$9b 2o6bo6bo2bo$9b2o4bobo4b2o$5bo10bo5bo3bo3bo$5bo11bo2bo4b2o$bobo2b2o10b 2o3bo5bobo$2o6b3o11bo8b2o$o2bobo3b2o11bo4bo$bo19bo3bo$21bo5b2o$22bo5bo ! #C [[ THUMBSIZE 2 THEME 6 GRID GRIDMAJOR 0 SUPPRESS THUMBLAUNCH ]] #C [[ HEIGHT 600 WIDTH 600 THUMBSIZE 2 ZOOM 10 GPS 8 AUTOSTART LOOP 7 TRACK -1/7 -1/7 ]]
