COMMENTS

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.
