Remy's Long Period Form Periodic Table
From H. Remy's 1956, Treatise on Inorganic Chemistry, Vol. 1, (Introduction and main groups of the periodic table), Elsevier, Amsterdam, p. 4, is what Remy calls a "Long-Period Form of the Natural System of the Elements".
This is a semi-lanthanide/actinide formulation, with Th-Pa-U shown as 6d metals, and the remaining actinides (Np, etc.) shown as transuranic counterparts to Pm, etc. The layout of Remy's table was based on ideas by Haissinsky in competition with Seaborg's formulation of 1945.
In the appendix there is a second "Table II" version of this formulation with shorter periods.

Walker & Curthoys' New periodic Table Based of Stability of Atomic Orbitals
By W. R. Walker and G. C. Curthoys, A new periodic table based on the energy sequence of atomic orbitals, J. Chem. Educ., 1956, 33 (2), p 69.
The abstract states:
"Since the theory of atomic and molecular orbitals has proven to be of such value in interpreting the data of inorganic chemistry, it is hoped that a new periodic table based on the energy sequence of atomic orbitals will be an aid to the further systematizing of chemical knowledge."

Sistema Periodico de Los Elementos (after Antropoff)
Mario Rodríguez Peña, PhD translates the spanish text on the Archive.org website:
"Periodic System of Elements, type Antropoff., 1956 Antropoff's periodic table was designed in Bonn (Germany) in 1926: https://www.meta-synthesis.com/webbook/35_pt/pt_database.php?PT_id=26 It was disused after the WWII (1945) in most of the countries, except Spain. This was dated in 1956 because Mendelevium (101) was discovered and accepted by IUPAC in 1955 and in 1957, the element symbols of Argon (18), Xenon (54), Einstenium (99) and Mendelevium itself changed to the current Ar, Xe, Es and Md, respectively."
Remy's Periodic Table II: The Short Period Presentation
Next to Remy's Long Form Periodic Table (H. Remy, Treatise on Inorganic Chemistry, Vol. 1, Introduction and main groups of the periodic table, Elsevier, Amsterdam, 1956, p. 4) is what Remy calls a "Short Period presentation" shown in the appendix, pages 838-939. The author comments:
"The form of presentation used in Table II in which the elements of the Long Periods are divided into two series, so that the short Periods determine the horizontal breadth of the system, is known as the Short Period presentation, as contrasted with the Long Period presentation in which the elements of the Long Periods are each time included in a single series.
"The Short Periods can then be broken up accordingly. Mendeléeff had already used the short-periodic and long-periodic mode of tabulation. The adjacent Table I sets it out as a form which is based directly on that already used by Mendeléeff, but completed by the insertion of the elements discovered subsequently."
