B3/S1e23iqr4c5k, a "tamed" version of B3/S1e23iqr

provided by wildmyron, has a rather nice

period-48 ship, moving diagonally and alternately creating and deleting a pair of dominoes on either side:

`#C https://catagolue.appspot.com/object/xq48_55zws0h884wmm1aezx7n2zy0c1w706/b3s1e23iqr4c5k/C1`

x = 15, y = 19, rule = B3/S1e23iqr4c5k

This is related to

this common period-24 puffer:

`x = 26, y = 21, rule = B3/S1e23iqr4c5k`

and to

this less common one:

`x = 16, y = 19, rule = B3/S1e23iqr4c5k`

2o2$2o$9b3o$9bo2bo$9bo$14bo$12bobo$4b2o7bo$14b2o$15bo$15bo7$8b2o!

The rule also has a very small

period-42 double-barrelled gun...

`x = 19, y = 3, rule = B3/S1e23iqr4c5k`

8b3o$2ob2o3bobo6b2o$8b3o!

...with an even smaller predecessor:

`x = 8, y = 3, rule = B3/S1e23iqr4c5k`

5b3o$2o3bobo$5b3o!

Adding a domino as an eater can make this single-barrelled:

`x = 19, y = 22, rule = B3/S1e23iqr4c5k`

9bo$9bo18$8b3o$2o6bobo3b2ob2o$8b3o!

Add eaters on both sides, and you get period-42 oscillators, e.g.

this (not seen in a soup yet):

`x = 19, y = 41, rule = B3/S1e23iqr4c5k`

9bo!
