Theme: Visual and logical

Rules: Variation of standard Fillomino rules. All polyominoes of same size besides 4 cannot touch. But all tetrominoes — polyominoes of size 4 — must be connected as in a LITS puzzle. All “4” clues have been replaced by letters indicating which tetromino type they belong to.

Answer String: For each cell in the marked rows, enter the area of the polyomino it belongs to. For the tetrominoes, instead of numbers use capital letters (L, I, T, S) in the appropriate cells. Start with the 6th row, followed by a comma, followed by the 14th row.
