Cycles of the unit digit of multiples of integers ending in 1, 3, 7 and 9 (upper row), and 2, 4, 6 and 8 (lower row) on a telephone keypad. Figure 1 is used for multiples of 1, 3, 7, and 9. Figure 2 is used for the multiples of 2, 4, 6, and 8. These patterns can be used to memorize the multiples of any number from 0 to 10, except 5.
1953 — Kapustinsky's table: Electron and neutron added to period 0; each period repeats once. There is a secondary diagonal relationship between the neutron (which decays to a proton, electron and antineutrino), and hydrogen. [26] 1967 — Sanderson's table: 2-8-10-14 stacked periods [35]
The configurations of the elements in this table are written starting with [Og] because oganesson is expected to be the last prior element with a closed-shell (inert gas) configuration, 1s 2 2s 2 2p 6 3s 2 3p 6 3d 10 4s 2 4p 6 4d 10 4f 14 5s 2 5p 6 5d 10 5f 14 6s 2 6p 6 6d 10 7s 2 7p 6.

Thus, the function f itself can be listed as: f = {((0, 0), f 0), ((0, 1), f 1), ((1, 0), f 2), ((1, 1), f 3)}, where f 0, f 1, f 2, and f 3 are each Boolean, 0 or 1, values as members of the codomain {0, 1}, as the outputs corresponding to the member of the domain, respectively. Rather than a list (set) given above, the truth table then ...
The first tables of trigonometric functions known to be made were by Hipparchus (c.190 – c.120 BCE) and Menelaus (c.70–140 CE), but both have been lost. Along with the surviving table of Ptolemy (c. 90 – c.168 CE), they were all tables of chords and not of half-chords, that is, the sine function. [1]
The definitive visualisation of all 118 elements is the periodic table of the elements, ... 0.158: 2.60: 3 × 10 −5: primordial gas 55 Cs Caesium [bo] 1 6 s-block ...
An opcode table (also called an opcode matrix) is a visual representation of all opcodes in an instruction set. It is arranged such that each axis of the table represents an upper or lower nibble, which combined form the full byte of the opcode. Additional opcode tables can exist for additional instructions created using an opcode prefix.
Ternary: The base-three numeral system with 0, 1, and 2 as digits. Quaternary : The base-four numeral system with 0, 1, 2, and 3 as digits. Hexadecimal : Base 16, widely used by computer system designers and programmers, as it provides a more human-friendly representation of binary-coded values.
