Pattern avoidance in Young diagrams
Okay, another try: is this notion of $D$ containing $D'$ equivalent to $P_D$ containing an induced copy of $P_{D'}$, where $P_D$ is the poset associated to the diagram $D$? |

Dynamics of RSK
@darijgrinberg: I think there is still something to flipping the octahedron upsidedown; I will try to understand precisely Example 5 from arxiv.org/abs/math/0703414. |

counting how many boxes from a given Young tableau contribute to hook length made out of two YTs
This is a potentially interesting question, but it would be helpful to have some context. For instance, you use the tag representation theory (and not combinatorics!) so presumably there is some representation lurking here, but you don't spell it out... |

Motivation behind the construction of Deligne and Lusztig
This recent article of Lusztig's also seems quite relevant: arxiv.org/abs/1409.8003. |

exceptional cases in Kazhdan-Lusztig
Can you clarify your notation here? Does the $1$ subscript denote untwisted affine Lie algebra? |

How to find the generic initial ideal?
By the way, it might be worth mentioning that this book is by Ezra Miller and Bernd Sturmfels. |
