I'm pretty sure that's new. And it's really nice.

It's definitely new -- congratulations!
Yup, fairly sure I would have noticed that if it had gone by already. Nice discovery! What search were you doing?

It combines nicely with extensible fireship technology:

Re: Spaceship Discussion Thread

Congrats on the new c/10 pushalong!
What about naming it "Coppergut"? Because at it's front is the copperhead's main head and at the back it has the little "tail" of a block.

That name seems fine, but before I say yes, does anyone have any other suggestions for a name?

There are lots of known completions with the same first seven rows. Might be some more matches hiding elsewhere, I didn't look really carefully. If a tail can be found to stabilize the next seven rows, that might be a new ship. But this may be search space that's already been covered pretty well. Not being a c/4 spaceship search expert, I wouldn't really know. googleplex Posts: 219 Joined: January 24th, 2018, 4:36 pm Re: Spaceship Discussion Thread googleplex wrote:here, a c/4 diagonal partial, part of my ikpx "flight tests" Code: Select all x = 14, y = 20, rule = B3/S23 2o$obo$obo$b3o$bobo$b3o$b2o$2bo$2b2o$bo$2bobo$3bo$5bo$3b3o$3bo$5b3o$7b 4o$7b4o$9bo3bo$12b2o!

I like Cottonmouth, it's easy to pronounce fluidly and has to do with snakes. I think Cottonmouth would be a good name for the pushalong.

While we're at it, "snake" could be made an (un)official nickname for a c/10 spaceship.

(There's some potential for confusion there, granted, but I don't see it being a problem in practice, anymore than -- say -- the existence of two different barges.)

Extending this C/8 partial at w10 g was negative:

Here's an update to the small c/4 orthogonal and 2c/5 orthogonal ship collections:

@wildmyron, I credited you as "WM" in ships-2c5-unique.rle since "AP" was already being used for Aidan Pierce. Do you want to be credited differently?

Sorry, I forgot to respond to this.

Thank you for continuing to maintain this collection and confirming the ships I posted are worth including. I'm happy for WM to be used as it is unambiguous and relates to me. If you used 3 letter initialisations then AJP would be appropriate, but it doesn't seem like there's any need for that and the two letter forms do format nicely.
