  1. I made a page about the E8 lattice and its application in sphere packing

    added cross-link with lattice (discrete subgroup)

    fixed capitalization throughout (notice that “Fields” in “Fields medal” is the name of a person: John Fields)

    (but mundane events like “medals” are better listed on the author’s page, instead of on a mathematical page, I have moved the comment to Maryna Viazovska)

    fixed spelling, readjusted wording and section headers

    added the math formatting $...$ where missing and fixed it where present: notice that in a formula you don’t put every term into its own math environment inside a text line, but just enclose the whole formula in a single pair of $...$

    merged the lines on sphere packings into a single subsection (now here) and adjusted the wording for clarity

    added author, publisher and date to:

    • Ursula Whitcher, Eight-dimensional spheres and the exceptional E 8E_8, AMS MathVoices Feature Column (Sep. 2022) [web]

    (this exposition would be more pertinent at sphere packing, so I am copying it to there)

    added pointer to the actual article being referred to:

    added redirect for “E8-lattice” (with the hyphen) so that the links long requested at shere packing problem now work
