Character	Chaotic

Eatsplosion is a cellular automaton with the rulestring B2n3-ekqy4c5e/S2-cn3-eky4aij5e. It is named for the evolution of the short table, t-tetromino, and pi heptomino. (this sequence is referred to as pi.)

Its forum thread can be found here. Its catalogue page can be found here.

Interesting still lives

The block is very common and useful. It can eat gliders:

x=6, y = 6, rule = B2n3-ekqy4c5e/S2-cn3-eky4aij5e bo$2bo$3o2$4b2o$4b2o!

or turn a pi into a glider and a pi.

x=7, y = 7, rule = B2n3-ekqy4c5e/S2-cn3-eky4aij5e 2o$2o4$4b3o$4bobo! #C [[ STOP 21 ]]

There is also the "hat with tail with block" (HWTWB), which is a pi eater:

x=7, y = 11, rule = B2n3-ekqy4c5e/S2-cn3-eky4aij5e b2o$2bo$b2o4$o5bo$3ob3o$3bo$3o2b2o$o4b2o! #C [[ STOP 14 ]]

Oscillators

Known periods include:

Periods 2-6

Period 8

Period 10

Period 15

Period 18

Period 36 and a few multiples of 36 as well

All periods above 125.

Just to demonstrate, here is a p125 glider loop:

There are a lot of these. The first known were these:

Afterwards the collection ballooned, due to spaceship searches by Goldtiger997 and testitemqlstudop.
