Thanks for all these comments. The blog has been updated where needed.

An upper bound for (weak) tree(3) would be helpful. It seems odd that one lower bound could be as low as 2^18-4 and yet the upper bound could be as high as f_SVO(3). This is a big range.

Does anybody know of better bounds for this particular value of the weak tree function ?

Cheers
