roots of permutations
True. My answer attempts to generalize further into equations in several variables. |

4-colorable graphs
It's even falser :-) In fact, there are graphs with high girth and high chromatic number. A graph with high girth looks like a tree around any vertex, so it avoids much more than just triangles. Proving that such graphs exist is perhaps even simpler than the explicit construction by Mycielski; it's basically a counting argument. |

Approaches to Riemann hypothesis using methods outside number theory
Is the "hidden operator" approach initiated by Dyson and Montgomery subsumed in the the Bost-Connes approach? en.wikipedia.org/wiki/Hilbert%E2%80%93P%C3%B3lya_conjecture |

How thick is the reciprocal of the squares
In the OEIS entry there's a comment by Frank Adams-Watters citing your paper. The first statement in the comment is "This set has zero density". Presumably this is wrong, and worth correcting? research.att.com/~njas/sequences/A108345 |

What's wrong with the surreals?
I actually remember one more disadvantage mention by Conway: equality is a defined relation, and a pretty subtle one at that. It's not too easy to figure out when two expressions for surreal numbers are actually equal. |

What can be tiled by T-tetrominoes?
The paper "Tiling rectangles with T-tetrominoes" by Korn and Pak seems to present some progress for non-rectangular simply-connected regions, mainly Theorem 11 in section 8. It doesn't seem like they have a complete answer though. citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.70.6847 |
