Interesting banana spark to beehive (The banana spark can be supplied in two directions):
If you replace the eater1 with an eater2 and add a block, you
almost get a p21 oscillator:
Code:
Select all
x = 17, y = 12, rule = B3/S23

[[ STOP 18 ]]
That implies that the combination of the beehive, two blocks and eater 2 has some niche uses as a catalyst, as a 'beehive spin', if you will:
Code: Select all
x = 17, y = 15, rule = B3/S23

EDIT: As a matter of fact, this catalyst is equivalent to the loaf spin reaction in
Baker's dozen, but is much cheaper and has higher clearance, at the cost of a higher recovery time:

are there any replacements for the tubs in these two situations?
Code: Select all
x = 35, y = 9, rule = B3/S23

if so then those catalysts are very useful (and could potentially monomerize a unix if they recover fast enough)

Note: the extra blocks are just so the products don't explode.
I don't know what you mean by monomerizing the Unix, apart from along the diagonal axis, but these recover in 12 generations, so I don't think that would be practical even if you were to successfully come up with a half-unix partial.
EDIT: Did you mean something akin to this when you mentioned monomerizing the unix?
Code:

yes, that catalysis can also be done with an eater2 or block
in general, if you want to combine an eater1 and a block catalysis like so, then you can replace it with an eater2 (as long as the eater2's catalysis creates a b2o$o2bo$o! when used on a block)

Yes, but its repeat time is too long for this reaction:
Code: Select all
x = 9, y = 15, rule = LifeHistory

i'm not sure about the potential of this catalyst but it looks cool and is a lazier (less specialized) way to make a transparent reaction happen if you ever wanted one, i guess
Code: Select all
x = 32, y = 12, rule = B3/S23

Is there any use for this catalyst?
Code: Select all
x = 13, y = 17, rule = B3/S23

(note that not all usual block catalyses can be replaced with eater2s)
Code: Select all
x = 12, y = 57, rule = B3/S23

The bottom one has a replacement:
Code: Select all
x = 11, y = 21, rule = B3/S23
