  • Normal sudoku rules apply.
  • Cells one chess knight's move apart may not contain the same digit.
  • English Literal Lines: Any three consecutive cells along a magenta line must contain digits with different number of letters in their english name, i.e., one each from the sets {126}, {378} and {459}.
  • Digits joined by a black dot are in 1:2 ratio, and digits joined by a white dot are consecutive. Not all possible dots are given.

Online in Sudokupad

Hint: (highlight below)

The action of the symmetry of order two in the coloring for the classes {126}, {378} and {459} is either trivial or has only one fixed class.

Solution code: Row 7 followed by row 4

By Neokart's recommendation gave these lines the "Literal" moniker.

since the intended break-in involves abstract group actions i added the math knowledge tag.

Cool constraint that I haven't seen before! It took me a while to figure out where to start colouring and lettering. Tricky break-in, but once I found it, everything just fell into place. Very nice!

Got the idea for the digit partition from @IkeManga at the CTC discord server. They used it with thermometers where the number of letters increase as well as the digits themselves! and i thought it would make for an interesting disambiguation step for entropic lines.
Glad you liked it!
