I was at 48 area from a troublesome final rotation from the center but then realized I could managed a 3-length swing without extra area if I put a glyph there (ended up being Calcifier), and I found another savings by putting Duplication on one of my storage hexes. Adding arm 2 and shortening arm 1's track got me down one more hex total.

Not what I'd call especially podium-worthy (which is probably all 42s) but I'll take it.
