- Quasigroup need invertibility. If in every row and every column any element shows only once is this then quasigroup?
I have a problem regarding what table is quasigroup. If we have multiplication table and that table is of the sudoku type is that quasigroup? See picture quasigroup.png. Is only (3) quasigroup?
