💖 CLASS.X 💖

okay bestie, gather round, because today we're talking about class.x — the icon, the moment, the polytope classifier. it lives in section 1 of the manual (User Commands energy only, obviously 👑), and it's here to classify reflexive polytopes. that's the whole vibe. no cap.

✨ NAME ✨

class.x, class-<num>d.x — classify reflexive polytopes 🦋

🌸 SYNOPSIS 🌸

class.x <Options> <ascii-input-file> <ascii-output-file>

💅 DESCRIPTION 💅

so there's the main character class.x, and then there's its little sibling programs class-<num>d.x — where <num> is literally one of 4, 5, 6 and 11 — and those work in different dimensions. multi-dimensional queen behavior fr fr.

and class.x itself? it defaults to dimension 6. that's just its factory setting, its resting state, its default slay ✨.

🎀 Options 🎀

  • -h — prints this information and gives you a command-line menu, so you can get more info than this manual even gives you. it's giving extra, and we love that for it 💅
  • -f or - — use as a filter, bestie. otherwise the parameters denote I/O files. pick your fighter.
  • -m* — various types of minimality checks. the * can be l, v, r, a (* ... lvra) 🔍
  • -p* NAME — specification of a binary I/O file. the * can be i, o, a, s (* ... ioas)
  • -d* NAME — specification of a binary I/O database (DB). the * can be i, o, s (* ... ios)
  • -r — recover: file=po-file.aux, use same pi-file 🩹
  • -o[#] — original lattice [omit up to # points] only. the # is optional, no pressure.
  • -s* — subpolytopes on various sublattices. the * can be v, p, h, m, b, q (* ... vphmbq) 🧚
  • -k — keep some of the vertices 🫶
  • -c, -C — check consistency of binary file or DB. two flags, one job, both valid.
  • -M[M] — print missing mirrors to ascii-output 🪞
  • -a[2b], -A — create binary file from ascii-input
  • -b[2a], -B — ascii-output from binary file or DB
  • -H* — applications related to Hodge number DBs. the * can be c, s, t, f, e (* ...cstfe) 🌈
