%N 2*alpha^4*e^(Pi/(4*alpha))*(e/2)^(1/4), where alpha is the fine structure constant A003673.

%C The geometric mean of a large N value in Planck square mass units in the midpoint isospin symmetry transition where exists superposition of protonic-neutronic degenerate matter in a spherical gravitationally collapsing system.

%C The sequence data corresponds to the Codata 2010 value alpha = 0.0072973525698 (= A003673, as of today). - _M. F. Hasler_, Feb 02 2014
