Outer Product differs from all other [[monadic operator]]s, which are written as a single [[glyph]], with the operand on the left. For [[backwards compatibility|historical reasons]], the outer product operator is a [[bi-glyph]] denoted as <source lang=apl inline>∘.</source>, and its appears on the right. | Outer Product differs from all other [[monadic operator]]s, which are written as a single [[glyph]], with the operand on the left.
