Scaled coefficients of Møller-Plesset perturbation theory.
Parameters a =  0.3767, b = -2.4945 and c =  5.6757
are chosen to make scaled coefficients of order of one in magnitude for all n.
Coefficient E1 = -182.62 is not shown because it is too small and out of scale

Convergence of summation approximants for the Møller - Plesset series
measured in growth of number of accurate decimal digits of summation results
with increase of n, number of used coefficients.
The summation methods are partial sums (red connected disks),
Pade approximants (blue circles),
quadratic approximants (green boxes),
cubic, quartic, fifth and sixth degree approximants
(triangles, diamonds, pentagonal and hexagonal stars respectively).
