%N Decimal expansion of the speed c/a in SI units [meter/second], where "c" is the speed of light in vacuum and "a" is the fine-structure constant (alpha).

%C Also phase velocity of de Broglie wave of a particle whose velocity is equal to the Bohr N1 velocity (A081800).

%C Note that this speed is greater than c.

%F c^2/V_n1 = A003678 / A003673 = A003678 * A005600 = A182999 / A081800.

%e Close to 41082358997 [m/s].

%Y Cf. A003673, A003678, A005600, A081800, A081801, A182999, A229952, A229962.
