In angstroms this constant is Yr = 911.2670....

The wavelengths are Yr*(0, 1, 4, 9, 16, 25, 36, 49, 64, 81, 100, ... = k^2).

The first differences Yr*(1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, ...).

The second differences Yr*(2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, ...).

Yr2= 2 * Yr = 0.000000182253410110... m.

k=1 is Lyman, k=2 is Balmer, ..., k=7 is Hansen-Strong.

In 1885, R was sure with 4 digits (A126252). For indigo, 9*243729/2 = 109678... .
