Does a 3D or 4D or arbitrary multi-D Life have glider guns?
Did Prof. Bays find ones in 3D Life?

Where can I find full/partial lists of still lives by cell count? Perhaps a more complete one than on the wiki?
x = 13, y = 8, rule = B3/S23

You're lucky.
See my posts in wwei23's still life thread. There there are all still lifes up to 13 bits (I'm working on the 14-bit). And then there are 16, 17 and 18-bit still lifes, which I copied in groups of thousands from Mark Niemiec's Life Page.
YOU ARE REALLY LUCKY

Has anyone tried looking at B3/S23 in the 4D vN neighbourhood?

I'm not sure, but it's probably not that interesting: no pattern can escape its initial bounding box without B0 or B1. It might be approximately equivalent in dynamics to B5/S12 or something similar in the 2D Moore neighborhood, which is to say, not very interesting.
x₁=ηx
V ⃰_η=c²√(Λη)
K=(Λu²)/2
Pₐ=1−1/(∫^∞_t₀(p(t)ˡ⁽ᵗ⁾)dt)

$$x_1=\eta x$$
$$V^*_\eta=c^2\sqrt{\Lambda\eta}$$
$$K=\frac{\Lambda u^2}2$$
$$P_a=1-\frac1{\int^\infty_{t_0}p(t)^{l(t)}dt}$$

Good point. So in vN every rule is either explosive or bounded? That's kind of boring.

Nope, see this:
x = 0, y = 0, rule = B02/S1V
o$b2o$bobo$3bo16$2o2$bobo$2b2o16$2o$2bo$b2o$3bo16$2o$obo2$2b2o16$4o$o2bo$o2bo$4o!


Well, any neighbourhoods other than Neumann ones are asymmetrical. This means that the neighbourhood graphs are not edge-transitive. Not so many related grids exist in higher dimensional euclydean spaces, and even finite many exist in lower dimensions AFAIK, but I might be wrong due to my possible false memory.

And there are even hexagonal _outer-totalistic_ b0-less rules with gliders.

Simplectic grids is an undiscovered area, today I did some related posts.
