### All Perfect Spaceship Speeds <= 20 Cells

I'd like to begin listing all the perfect spaceship speeds less than or equal to 20 cells in outer-totalistic and non-totalistic rules alike.
I'll edit this list as we go.

Orthogonal
c:
c/2: LWSS (b3s23)
c/3:
c/4:
c/5:
c/6:
c/7: Loafer (b3s23)
c/8:
c/9:
c/10:
c/11:
c/12:

Diagonal
c/2: Glider (b3s23)
c/3:
c/4:
c/5:
c/6:
c/7:
c/8:
c/9:
c/10:
c/11:
c/12:

Life is hard. Deal with it.
My favorite oscillator of all time:
`x = 7, y = 5, rule = B3/S2-i3-y4i4b3o\$6bo\$o3b3o\$2o\$bo!`

There's numerous adjustable spaceship families that have less than 20 cells.
