This script will compute the pairing of lie coalgebra and lie algebra elements. Along the top row, enter lie algebra elements in the form "[[[[[2,1],1],1],1],[2,1]]" (commas optional) using the numbers 0-9. Along the left side, enter lie coalgebra elements in the form "1211121" also using the numbers 0-9. The "+/-" buttons add/remove rows and colums. The "compute pairings" button does computations. Hide instructions.
