New Stable H-to-G

[knightlife]

I have finally made my first stable converter!

Stable H-to-G:

Code: Select all

x = 21, y = 24, rule = B3/S23
4b2obo$4bob2o2$5b5o$2o2bo4bo$o2bo2bo$bobob2o$2obo5bo9bo$3bo4bobo6b3o$
3b2o2bo2bo5bo$8b2o6b2o9$7b3o$8bo8b2o$8b3o6bo$18b3o$20bo!

It is bigger than the simple beehive H-to-G but twice as fast to recover.
This one is fully stabilized in only 37 tics versus 75 tics for the beehive version.

Edit: I have not been able to get image to appear, not sure why.
Got it. I think there was a carriage return preventing the display

How about:

Code: Select all

x=15, y=19
2o$bo$bobo$2b2o11$b3o$2bo8b2o$2b3o6bo$12b3o$14bo!

Remove the upper Eater, and a B-heptomino appears on Gen 44. But I ran out of time and couldn't find a way to suppress the garbage...

Code: Select all

x=16, y=14, h=1, v=5
12b2o$12bobo$14bo$14b2o6$3o$bo8b2o$b3o6bo$11b3o$13bo!

What about this?

Code: Select all

x = 21, y = 19, rule = B3/S23
2$10b2o$10b2o3$17b2o$17b2o3$5b3o$6bo$6b3o!

Quite fast and small.

That is hard to beat. Maybe you can do something with this H to 3G that produces a forward glider:

Code: Select all

x = 142, y = 93, rule = B3/S23
82b2o$82b2o7$61b2o$60bo2bo$61b2o7$65b3o$66bo$66b3o12$112bo$111bobo$

Almost stable.
The beehive needs to be rebuilt with the two backward gliders...

Edit:
I just found this way of regenerating the beehive with a "reset" Herschel:

Code: Select all

x = 31, y = 20, rule = B3/S23
29b2o$29b2o3$b3o$bo$2o2$8b2o$7bo2bo$8b2o3$5b2o$5b2o3$12b3o$13bo$13b3o!

Amazingly, the reset circuitry (just one added block) does not interfere with the H to 3G.
The reset is actually from your H to G minus one block, it creates a beehive.
The second (ghosted) Herschel needs to appear 132 tics or more after the first.
