Decimal expansion of k = log(262537412640768744)/Pi.
Note that 262537412640768744 = 24*10939058860032031 = 2^3 * 3 * 10939058860032031, is the nearest integer to the value of Ramanujan's constant e^(Pi*sqrt(163)) = A060295.
By construction, this constant here is very close to sqrt(163) = A210963.

Examples
