%N A219388 Basic quantic arrangement for the 1 to 120 planetary electrons and elementary periods (circles I to XX) distributed by energy levels.
%C A219388 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.
%C A219388 Hence for the periodic table,the distribution
%C A219388 120 119
%C A219388 88  87 118....113
%C A219388 56  55  86.....81 112....103

%C A219388 12  11  18.....13  30.....21
%C A219388   4   3  10......5
%C A219388   2   1.
%C A219388 From right to left this is the ADOMAH periodic table (2006) in A217927(n).
%C A219388 A rotation of 180 degrees leads to the (B) periodic table in A217927(n).
%C A219388 Note that the rotation of the example gives
%C A219388       1
%C A219388     2 2
%C A219388   3 3 3
%C A219388 4 4 4 4
%C A219388 5 5 5 5
%C A219388   6 6 6
%C A219388     7 7
%C A219388       8.
%C A219388 Hence the (B) table in A217927.
