32-digit values of the first 100 recurrence coefficients for orthogonal polynomials relative to the weight function w(x)=exp(-exp(|x|)) on [-Inf ,Inf] are computed by an 8-component discretization procedure using the routine sr_hypexpsymm(nofdig,N), with nofdig=32, N=100, and dig=36 entered when prompted. The value dig=36 has been determined by the routine dig_shypexpsymm(100,34,2,32) (which may take as long as two hours to run). The software provided in this dataset allows generating an arbitrary number N of recurrence coefficients for different precisions.
