* The three 1-modifers Cells (<code>𝔽˘</code>), Each (<code>𝔽¨</code>), and Undo (<code>𝔽⁼</code>) are equivalent to using a right-[[operand]] of <code>¯1</code> with the 2-modifiers Rank (<code>𝔽⎉¯1</code>), Depth (<code>𝔽⚇¯1</code>), and Repeat (<code>𝔽⍟¯1</code>). Therefore the 2-modifiers are circled versions of the 1-modifiers (except in the case of Undo/Repeat).
* The three 1-modifers Cells (<code>𝔽˘</code>), Each (<code>𝔽¨</code>), and Undo (<code>𝔽⁼</code>) are equivalent to using a right-[[operand]] of <code>¯1</code> with the 2-modifiers Rank (<code>𝔽⎉¯1</code>), Depth (<code>𝔽⚇¯1</code>), and Repeat (<code>𝔽⍟¯1</code>). Therefore the 2-modifiers are circled versions of the 1-modifiers (except in the case of Undo/Repeat).
* Under (<code>𝔽⌾𝔾</code>) is in principle equivalent to <code>𝔾⁼∘𝔽○𝔾</code>. Therefore, <code>⌾</code> is a combination of the glyphs <code>∘</code> and <code>○</code>.

== The Name BQN ==
The name "BQN" was originated as a forward iteration of the letters of APL, and [https://mlochbaum.github.io/BQN/#what-kind-of-name-is-bqn "happens to match the capitals in 'Big Questions Notation'"].
[[Marshall Lochbaum]] [https://chat.stackexchange.com/transcript/message/54753804#54753804 recounts], "I obtained 'BQN' by moving each letter in 'APL' forward by one in the alphabet. I'd come up with the backronym 'Big Questions Notation' by the time I realized N doesn't come after L."  Marshall commented further on this in [https://www.arraycast.com/episode-7-transcript Episode 7 of the Array Cast], in response to a question starting at the 11:29 mark.
