I wanted to see what b4s23 would be like, but added the 3a and 3i because they're the maximal transitions such that patterns can escape their bounding diamonds and boxes respectively.
It is a rule with a great many natural oscillators comprised of still lifes perturbing Life's traffic light predecessor (that, in this rule, is instead the most common predecessor of xp21_ehhhe). The loaf is the successor of one with a corner cell missing, that is also a common evolutionary sequence that produces a clean explosion,
Code: Select all
x = 3, y = 3, rule = B3ai4/S23

There is also a seminatural linear growth pattern, an (8,8)*c/58 puffer comprised of two separate halves, each with a glide-symmetric loaf frontend, that are separate but stabilise each other, they can be displaced in a few ways, causing several variants. yl58_1_8_55a95d61dacd0e04fb9e8a38f38fa305, yl58_1_22_50e18ebfe66e6a7815b2f0522722c56a and yl58_1_48_28c7b679b03ed08e57ca12bdf19630f1 are some, I can't link the others due to Catagolue's object page not identifying linear growth patterns
here is its least messy version's minimal form

Convince others to apgsearch it with me (perhaps I am being optimistic but I think it is quite a nice rule :-)
Run programs for explicitly searching for oscillators instead of only using apgsearch
Find more traffic-light-predecessor-displacing hasslers (perhaps by explicit search programs also), see whether any mechanisms are interoperable with existing ones with the same numerators to form oscillators with periods of the sum of their denominators (the hasslers in the oscillators shown above displace them by 3*c/8,3*c/11,4*c/17,5*c/24,6*c/21, but the 3*c/8 and 3*c/11 ones aren't because the 3*c/8 requires the total period to be a multiple of 4 and the 3*c/11 would interact with the xp4's, and two meeting orthogonally with a displacement of 8 cells will displace themselves away by 4*c/22 (as shown in the first xp39), and with 7 cells' displacement by 12*c/21)
Find something like Life's Eater 3 but with a beehive instead, stabilising the perturbation that cause beehives on their lines of symmetry to lose their end cells, then become filled 4*1 then 2*3 arrays temporarily before returning to their initial state, but only requiring perturbations on one side (providing an alternative 6*c/21 traffic-light-predecessor-hassling mechanism, and allowing the xp27 to be reduced by only including a quarter of its original self)
Find more periods and speeds of spaceships (specifically, c/2 and (1,1)*c/4 seem possible, from partials' frontends)
Find additional natural (or semi-natural) elementary spaceship mechanisms
Find a conduit that displaces the traffic light predecessor (or perhaps a different one) sufficiently far (and with sufficient clearance) to insert them perpendicularly, to build arbitrarily large loops of arbitrarily high periods
Prove Turing-completeness
Construct spaceship gun (probably for the xq20)
Construct stable reflector (to perhaps find upper bound on the minimum period above which all exist)
Prove omniperiodicity
Construct geminoid
DONE:
Construct (or otherwise find, if it's done by something like sep_stdin) a (8,8)c/58 corderoid
