Some Lodges and rituals explain these symbols as lessons in conduct: for example, Duncan's Masonic Monitor of 1866 explains them as: "The square, to square
Square packing in a square Square packing in a square Square packing in a square is a packing problem where the objective is to determine how many squares of side 1 (unit squares) can be packed into a square of side "a". If "a" is an integer, the answer is "a", but the precise, or even asymptotic, amount of wasted space for non-integer "a" is an open question. The smallest value of "a" that allows the packing of "n" unit squares is known when "n" is a perfect square (in which case it is ), as well as for "n" = 2, 3, 5, 6,
