Number of groups of squarefree order
This post is a sort of footnote to the previous post, Estimating the number of groups of a given order. The following is taken from an answer to a question on Stack Exchange. In general there is no formula f(n) for the number of groups of order up to isomorphism. However,

John Conway et al [1] give the name gnu(n) to the number of groups of order n, where “gnu” stands for group number. This function has been studied since the 19th century, but I don’t know whether there has ever been a standard notation for it. Mathematica calls it FiniteGroupCount.

OpenAI was never quite like other generative AI startups — or other startups period, for that matter. Its governance structure is unique and what ultimately led to the abrupt ousting of CEO Sam Altman on Friday. Even after it transitioned from a nonprofit to a “capped-profit” company in 2019, OpenAI

I’m a sucker for a new coding font. I generally don’t think what coding font you use affects productivity in any significant way (unless it’s distracting) so farting around and switching it up is just a fun little thing to do. Like pushing around the furniture in your room or
