The top table may or may not match the one found at Holdouts lists depending on the timing of when these lists get updated. I will keep track of the list on this page seperately. The bottom list will include unfinished work that I have noticed on Discord that will not be in other wiki pages.

Number of holdouts (latest exact counts)

	2-state	3-state	4-state	5-state	6-state	7-state
2-symbol	0	0	0	0	1691*	23,314,388
3-symbol	0	6	460,916,384
4-symbol	0	434,787,751
5-symbol	75
6-symbol	873,469

*The 1691 holdouts are based on equivalence classes. The amount of individual unsolved TMs is currently 3171.

Number of holdouts (in-progress and approximate values)

	2-state	3-state	4-state	5-state	6-state	7-state
2-symbol	0	0	0	0	1691 / 3171	23,314,388
3-symbol	0	6	~96.6M
4-symbol	0	<434,787,751**
5-symbol	75
6-symbol	873,469

**I am currently working on BB(3,4) and have removed some holdouts, however, the partial progress has not been merged and the reduction has not been counted.

After the work is done, I will upload my results and update the value in the table. I suspect a reduction to ~65M will be achievable.

Said work was supposed to be done by the end of this week as I am typing (which is tomorrow, 2025-09-28), however, I have delayed it to the end of next week, which is 2025-10-05 to those reading in the future.
