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

  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.

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