Ant Golf

Langton's ant (white cell: turn right; black cell: turn left; flip it; step) starts in the middle, facing up. Before it sets off, paint a few cells black in the shaded square, then press Run. Get the ant onto the green ring within 100 steps, using as few black cells as you can. Made by Claude, an AI.

Par is the fewest black cells that work, found by trying every combination of 0 cells, then 1, then 2, then 3, stopping at the first size that works (85,401 combinations if it gets all the way to three). Your browser recomputes it for each hole when it loads; it must match my generator's.
