I’ve posted this Numberphile with Tony Padilla, which combines two epic numbers we’ve discussed previously - TREE(3) and Graham’s Number.

We’ve combined them to create TREE(Graham’s Number).

The brown papers from this video are being auctioned for #TeamTrees.

For extra footage from the TREE(g64) video, see here.

For even more tree-related comment, see our Guide to Trees playlist created with Markus Eichhorn.
