Abscissas and weights for Gaussian quadratures of high order

Weights and abscissas are prese nted for the Gaussian quadrature rules of order n= 16, 20, 24, 32, 40, 48. These constants were computed on Standards Automatic Computer b y t he method described and have passed a number of checks with about 20 p laces of decimals. Values of the weights and abscissa s are also available for n= 64, 80, and 96.
