Today's knight's tour. #mathart

A single-line drawing arising from an open knight's tour of an 81x81 chessboard. If you think of the 9x9 array of 9x9 subtours as a 3x3 array of motifs, you'll find that you can interpret the drawing as a 3x3 magic square. #mathart

An open knight’s tour of a 33x33 board, and an open knight’s tour of a 99x99 board. Both use the same 11x11 tour as a motif, and both follow a Peano-curve-like path through the array of 11x11 cells.

Here's a preview of my Davidson College honors student's (inspired by Robert (Bob) Bosch work) lenticular dice mosaic of Katherine Johnson & Maryam Mirzakhani. Our piece will hang next month on Mercer Island in a math & art exhibit hosted by the Seattle Universal Math Museum (SUMM).

A knight's tour of a 32x32 chessboard. The knight's path can be traced without lifting one's writing implement from the surface of the paper. This tour is close to having 180-degree rotational symmetry and vertical and horizontal mirror symmetries. #mathart #chess

A knight's tour of a 32x32 chessboard. The knight's path is unicursal. If you start in the lower left corner and follow the path move by move, you will visit each square once and only once and end near the lower right corner. #mathart #mathsart #orms #chess
