The Catagolue object pages of those two ships are

Unfortunately I cannot find specific
ikpx2_stdin hauls in
this list where the spaceships occurred; it is possible that the hauls were discarded to save space.

There was a soup listed as having a lifespan of 5250 on the
old soup search site, clicking the 'RLE' link for it leads to nowhere but the URL itself has the soup's RLE embedded in it. Sadly, on running the soup it just produces a puffer and a p4 oscillator which I assume must have confused the census program?

Are there any spaceships that work in both B35/S23 and B3/S23?
With a moderately weird setup LLSSS can search for ships that are shared* between the two rules. With further weirdness it can search for arbitrary width ships. When such a search terminates with no results it shows, barring bugs, that there are no (finite) ships at all. This was easily and quickly the case for c/2, c/3, 2c/4, and 2c/5.
On the other hand, c/4, c/5, c/4d, and c/5d did not complete with 8G of RAM, but what little poking I've done so far for finite widths hasn't turned up anything so the jury is still out.
Perhaps more results later when I have more RAM available to allocate to the question or when more searches at finite width have completed.
*My definition of "shared" here is the strictest possible, namely that not only is the collection of cell coordinates the same in one generation, but the evolution through all generations is identical (and therefore at no point is the absence/presence of B5 used). Contrast with a weaker definition where one generation must match but intervening generations could proceed differently as long as they looped back around to the same matching generation.

You could go even weaker than copperhead vs. goldenhead or CGoL pentadecathlon vs. B3/S238 pentadecathlon, if you allow the period/displacement to be different and require only that one phase coincides. Unlike the strict requirement of identical evolution across all phases, this is not transitive (if A has a common phase with B and if B has a common phase with C, it does not yet follow that A has a common phase with C).

All the search programs for which I have even a vague idea of the operation principles (gfind, LSSS, LGOL, LLSSS) are very insistent on knowing the states of all generations. I would in fact assume most if not all successful search programs are going to be similarly insistent.
Given that it's sort of hard to search for a weaker definition (What is "golden head"? I'm going to assume we mean "matching in one generation and in velocity"). The only thing I can think of that's even vaguely close is you could search in the product CA (2x2 = 4 states, where each cell tracks a state for each rule and they evolve independently) and require that all cells in one generation be one of the two matching states. Alas, I am unlikely to be able to help any further as for both of mine (LGOL and LLSSS) the assumption of 2 state CA has beyond sailed.

No worries - my roommate works at a research lab, which has a supercomputer. I will ask him to run gfind for 24 hours.
EDIT: He said that it can only be run for 6 minutes at most at a time without official approval, before needing a 30-second cooldown. Will it work?
EDIT 2: He said that if it is run for more than 9 minutes, there are probably no results.
EDIT 3: No results after 6 minutes. Have to stop now.

My understanding is that supercomputers rely on parallel architectures for their speed, but gfind is single threaded; it is not written for parallel computing. I imagine a gfind search on a supercomputer wouldn't be much faster than on a home desktop.
The programs I'm aware of that utilize multithreading are LSSS, LLSSS, ikpx2, and qfind. Of these, only some variant of LLSSS has been configured to look for ships that work in two desired rules at once. It wouldn't be hard to modify qfind for this purpose, but qfind will always be at a fixed width, while Amling's LLSSS searches are for arbitrary-width ships. Thus these searches can eliminate the possibility of
any ships of the chosen period and speed (if Keith has enough RAM to complete the search).

Neither is "actually explosive" (to the extent that 'explosive' is well-defined). Those are just puffers. It seems like apgsearch identification algorithm classifies these as "zz_EXPLOSIVE" for some reason.
