Computation of the Landau function g(n)


Download in the same directory the two files


the MAPLE code file proggden

and the data file superch2.m


Open a MAPLE sheet and type
read proggden:
then type
functLandau(n,1):
for some n between 166 and 10^{15}. The meaning of the second argument 1 is explained in the MAPLE code file.

The method of computation of g(n) is described in the paper :
