32-digit values of the first 64 recurrence coefficients for orthogonal polynomials relative to the weight function w(x)=x^a*exp(-x)*log(1+1/x) on [1,Inf], a=1, are computed by a 1-component discretization method using the routine sr_explog_inf(32,64), where dig=48 and a=1 have to be entered when prompted by the routine. The value 48 of dig has been determined by the routine dig_explog_inf(64,32,4,32) where a = 1 has to be entered when prompted. 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.
