6 X 6 square of orbital p filling elements in Mendeleyev-Seaborg or Janet-Tarantola periodic table.
The sequence is considered full if we assume that all elements with 8 shells or more, i.e. of periods 8 and higher in Mendeleev's periodic table, have extremely unstable nuclei (extremely short half-life.)
The atomic numbers of elements in each block are
s-block: 1,2, 3,4, 11,12, 19,20, 37,38, 55,56, 87,88 for Mendeleev's periodic table (Cf. A160914)
s-block: 1,2, 3,4, 11,12, 19,20, 37,38, 55,56, 87,88, 119,120 for Janet's periodic table (Cf. A160914)
p-block: 5..10, 13..18, 31..36, 49..54, 81..86, 113..118 (Cf. A138469)
d-block: 21..30, 39..48, 71..80, 103..112 (Cf. A199934)
f-block: 57..70, 89..102 (Cf. A217923)
