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:

A width 12 even symmetric search with ntzfind (rokicki's). I noticed a repeating component, and substituted a Copperhead in for another part and got the ship.

EDIT, C/10 w7 a is negative, best partial:

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?

Other potential possibilities: "Cuttlefish" (reused from a suggestion for Copperhead itself), "Chalcocite" (the mineral form of Cu₂S, as this ship has two Copperhead-like components and one distinct one), or simply "78P10H1V0".

Cottonmouth -- sticking with the "snakes starting on C" theme.

Cottonmouth -- sticking with the "snakes starting on C" theme.

I was reserving that name for a new velocity, and would have named the fireship it. Fits here well, though.

Snakes starting with C:

Cylindrophis

Colubridae

Candoia

Calabar python/Calabaria

On the topic of Spaceships, how can I help?

A for awesome wrote:"Chalcocite" (the mineral form of Cu₂S, as this ship has two Copperhead-like components and one distinct one).

That's my favourite suggestion so far.

Check the fourth and fifth rows from the bottom in Golly's Patterns/Life/Spaceships/c4-orthogonal.rle. 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.

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.)

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.
