An open knight's tour of a 64x64 chessboard. The knight starts in the lower left corner, finishes near the lower right corner, and visits each of the 8x8 squares (that look like a U or a rotated U) in the same order that they'd be visited by a third-stage Hilbert curve.

Japanese theorem:
no matter how one triangulates a cyclic polygon, the sum of inradii of triangles is constant.

The Cistercian monks invented a numbering system in the 13th century which meant that any number from 1 to 9999 could be written using a single symbol.
