In his last publication (see the reference, leaflet 5 (number 12)), Janet (1849-1932) wrote: Arrangement quantique de base,des électrons planétaires,(1 à 120),et des périodes élémentaires (cercles I à XX) disposées par niveaux d'énergie. This corresponds to 1,2,3,4,4,3,2,1 terms (*) of 8 to 1. In the example.
Hence for the periodic table,the distribution
120 119
88 87 118....113
56 55 86.....81 112....103
38 37 54.....49 80.....71 102....89
20 19 36.....31 48.....39 70....57
12 11 18.....13 30.....21
4 3 10......5
2 1.
From right to left this is the ADOMAH periodic table (2006) in A217927(n).
A rotation of 180 degrees leads to the (B) periodic table in A217927(n).
Note that the rotation of the example gives
1
2 2
3 3 3
4 4 4 4
5 5 5 5
6 6 6
7 7
8.
Hence the (B) table in A217927.
(*) See A090281.

The 20 numbers are presented each one in a circle.
The columns are what is now quantum numbers l=0,1,2,3.
