Does $\binom{2n}{n} \equiv 2 \pmod p$ ever hold?
@BenjaminDickman: Thanks for reminding me about mathoverflow.net/a/165441/22971; I will check how relevant it is. |

@The Masked Avenger: I've just made the computation - nothing to write home about. (I have troubles fitting the results into this comment, but they are absolutely non-illuminating, anyway.) |

@Felipe: having thought for a little while, I don't see any immediate relation. It has to do with $y^{2(n-1)}-x^{2(n-1)}$ being quadratic residues though. |

List of integers without any arithmetic progression of n terms
@Timothy: my wild guess is that considering progressions with just two carefully chosen differences ($n$ and $n-1$?) may suffice. I think the first step would be to verify this numerically. |

Having my answer submitted, I noticed a comment by Wolfgang which appeared while I was typing. My answer is based on the very same idea, of course. |

Subgroup cliques in the Paley graph
This is certainly a non-trivial improvement, but still well off from what I'd be happy to have here... |

Subgroup cliques in the Paley graph
@Felipe: that's interesting. What the improvement is like? Is it effective / explicit? (And thanks for fixing the typo.) |
