Subject: [Computer-go] Number of 3x3 patterns
I could not find the number of 3x3 patterns in Go, if used all symmetries.
Can anybody give me a hint, were to f
table to map the pattern
IDs to a set of consecutive index, 0-1251.

Ah. That makes sense. It's a pattern centered on a possible next move. Very
cool. Tysvm for explaining.

I don't see how "leave the center empty" works as a valid case, assuming
this it just any valid 3x3 window on the board. Given bots playing each
other, there can be 9x9 clumps of a stone of the same color. I can see it
being argued there is no computational value in this specific pattern
instance.
I get 1107 (954 in the middle + 135 on the edge + 18 on a corner).
Álvaro.

Thanks, but I need them reduced by reflection and rotation symmetries
(and leave the center empty so 3^8 + 3^5 + 3^3 and than reduce)

If you are considering only black stone, white, empty and border,
ignoring symmetry, wouldn't it be
3^9 + 3^6 + 3^4
3^9 for patterns away from the border, 3^6 for near the sides and 3^4
near the corners, assuming you are also interested in the center value.
This makes 20493, then you need to

I could not find the number of 3x3 patterns in Go, if used all symmetrie
s.
Can anybody give me a hint, were to find. Harvesting 4 games I get
1093:)
Thanks, Detlef
