The idea of this blog, that I was long too lazy to put into action, was as a collection of smaller observations that are not exactly paper worthy. That, and the obvious procrastination from doing actual work.
The final kick was the pandemic, and a question that Yue Ren asked me recently. It occured to me that I had answered the question before, several times, to several people, but had not really recorded the answer. That will be the topic of the actual first post.
So if you look for smaller musings and nonsense, between combinatorics, algebra and geometry. Then that somewhere is here, for this result and others like it. Sometimes also other things, who knows.
