We improve the lower bound on the extremal version of the Maximum Agreement Subtree problem. Namely we prove that two binary trees on the same n leaves have subtrees with the same β₯ c log log n leaves which are homeomorphic, such that homeomorphism is identity on the leaves.

In this paper we derive an improved upper bound on the average vertex degree, 6. needed to ensure that: Vc > 0 and n sufficiently large, a random n-vertex graph with at least (6 + E)&! edges is almost certainly not 3-colourable. @

## Abstract We draw the __n__βdimensional hypercube in the plane with ${5\over 32}4^{n}-\lfloor{{{{n}^{2}+1}\over 2}}\rfloor {2}^{n-2}$ crossings, which improves the previous best estimation and coincides with the long conjectured upper bound of ErdΓΆs and Guy.
