The article mentions both 1917 and 1918 as the alphabet reform, which is it?

Letter Ordering

(1). The original JIUKEN typewriter, pictured in the main article, exhibited the following (semi)vowel arrangement:

 Й I Y - E - - -
 - Ы - - A - - O
 - - - - - И - -

The first four-letter block, to the left, fits perfectly into the empty space(s) of the second four-letter block, to the right, thus pointing to an initial arrangement of the form:

 E Й I Y
 A - Ы O
 - И - -

or simply:

 E Й I Y
 A И Ы O

The original order would thus appear to have been alphabetical: A–E, И–Й, I, O–Y, Ы.

(2). The block Й–I_Ы–Y was then later moved to the left, due to issues of letter frequency, being replaced, after displacing И downwards, by the most frequent ten consonants, ordered alphabetically: B, Δ, K–T, as suggested by the simple observation that, by moving the M–Π–Γ diagonal(ly) upwards, an ^H_M^Π_P block suddenly appears, representing the four consecutive consonants M–P, ordered clockwise, from the bottom left, with an C—T visible on the lower row, the remaining B–Δ, K–Λ placed symmetrically, with respect to the initial (semi)vowel block, as follows:

 - - * H Π - - -
 B K * M P * Λ Δ
 - - C * T - - -

the four stars representing the remaining vowels: A, E, И, O.

(3). The remaining least frequent ten consonants, ordered alphabetically, are then split into two groups of five, which, after the middle two consonants, Φ X, are placed symmetrically, at the extremities of the middle row, become two groups of four.

In a now familiar fashion, similar to the one employed at arranging the (semi)vowels, the former block becomes: ^Γ_Б³_Ж , while the latter, employing a doubly–reversed order, both horizontally and vertically, becomes: ^Ш_Щ^Ц_Ч .

The latter block is then inserted in the middle of the former, yielding: ^Γ_Б^Ш_Щ^Ц_Ч³_Ж , as a result.

After displacing C to the left, by moving the M–Π–Γ diagonal(ly) downwards, Б and Ч are also displaced, and relocated at the extremities of the last row, by moving both Ш and 3 diagonally downwards–left.

(4). The diphthong Э, corresponding to the Latin & Nordic Æ and Germanic Ä, then takes the former place of the visually similar 3, while the remaining two, Я Ю, become the new extremities of the last row.

(5). Likewise, the visually similar Ж and X switch places, thereby making Δ adjacent to both Ж and 3, since both digraphs (ΔЖ, Δ3) exist in both Russian and Ukrainian.

(6). The two yers and the yat are then inserted symmetrically, at the last row's (inner) extremities, with the hard sign displacing K upwards.
