↑ The origin of the name is not known. However, krake means octopus in German and the name seems to have first appeared in Achim Flammenkamp's census no later than 2004.
↑ Headerless RLEs of the collisions are b2o5b3o2bo$o2bo8b2o$b2o9bobo5$3bo$3bo$3bo! (11 escaping gliders, final population 472) and 5b2ob2o$5b2ob2o4$6b2ob2o$b2o3b2ob2o$o2bo$b2o$4b3o$4bo$5bo! (3 escaping gliders, final population 112).
