B24/S013 and B24/S13

[LaundryPizza03]

I was interested in attempting to find a c/1 photon in B24/S013. Here's what I do know:

• It is too wide to find using gfind.
• The narrowest rear-end partial has the following form, which can be turned into a tagalong:

  Code: Select all

  x = 20, y = 19, rule = B24/S013

• There are 41 distinct front-end partials with width 36 and length 23. All are asymmetric.

  Code: Select all

  x = 36, y = 22, rule = B24/S013

• It may actually be easier to find an asymmetric ship.
• It can contain no dots, since a dot would fill the spot behind it.

It would be interesting to find other speeds as well.

For reference, here is the known spaceship in B24/S13 (Jason Summers, 1999), plus a smaller one I found with LLS. The latter might actually be the smallest by bounding box.

Rlifesrc can’t deal with these.
I’ve just tested this morning.

No more result. It told me when the search started.
