  Recently reported computations have been extended to give ten more decimals
of accuracy in the ground state energy of the Schrodinger equation for the
idealized Helium atom. With the F basis - Hylleraas coordinates with negative
powers and a logarithm of s - carried to the fiftieth order (N = 24,099 terms)
we find the eigenvalue E = -2.90372 43770 34119 59831 11592 45194 40444 66969
