<p>32-digit values of the first 100 recurrence coefficients for orthogonal polynomials relative to the weight function w(x)=x^a* (1-x^c)^b on [0,1], a=-1/2, b=-1/2, c=3, are computed by a moment-based method using the routine sr_alg(dig,32,100,-1/2,-1/2,3), where dig=180 has been determined by the routine dig_alg(100,-1/2,-1/2,3,172,4,32). The results are in complete agreement with the first 26 recurrence coefficients given to 25 digits in Table 22 of Paul F. Byrd and David C. Galant, &quot;Gauss quadrature rules involving some nonclassical weight functions&quot;, NASA Technical Note D-5785, National Aeronautics and Space Administration, Washington, D.C., 1970. The software provided in this dataset allows generating an arbitrary number N of recurrence coefficients for arbitrary a &gt; -1/2, b -1/2, c &gt; 0, as well as for different precisions.</p>
