32-digit values of the first 62 recurrence coefficients for orthogonal polynomials relative to the weight function w(x)=x^a*exp(-x)*log(1+1/x) on [0,1], a=5, are computed by a 1-component discretization method using the routine sr_explog_fin(32,62), where dig=36 and a=5 have to be entered when prompted by the routine. The number 36 of digits has been determined by the routine dig_explog_fin(62,32,4,32). The software provided in this dataset allows generating any number N<=65-ceil(a/2) of recurrence coefficients for any nonnegative integer a, and for any precision of less than, or equal, 32 digits.
