“…, t (ℓ) ) as a labelling of (the diagram of) µ, where t (r) is the restriction of t to µ (r) . In this way, we talk of the rows, columns and components of a tableau t. For example, 1 ) is a µ-tableau then define Shape(t) = µ, so that Shape(t (r) ) = µ (r) , for 1 ≤ r ≤ ℓ. If t −1 (k) = (r, c, l), then we set comp t (k) = l. A µ-tableau t is standard if its entries increase along the rows and down the columns of each component.…”
