U+29FF Miny
U+29FF was added in Unicode version 3.2 in 2002. It belongs to the block
This character is a Math Symbol and is commonly used, that is, in no specific script.
The glyph is not a composition. It has no designated width in East Asian texts. In bidirectional text it acts as Other Neutral. When changing direction it is not mirrored. The word that U+29FF forms with similar adjacent characters prevents a line break inside it.
The Wikipedia has the following information about this codepoint:
In mathematics, tiny and miny are operators that yield infinitesimal values when applied to numbers in combinatorial game theory. Given a positive number G, tiny G (denoted by ⧾_{G} in many texts) is equal to {0{0G}} for any game G, whereas miny G (analogously denoted ⧿_{G}) is tiny G's negative, or {{G0}0}.
Tiny and miny aren't just abstract mathematical operators on combinatorial games: tiny and miny games do occur "naturally" in such games as toppling dominoes. Specifically, tiny n, where n is a natural number, can be generated by placing two black dominoes outside n + 2 white dominoes.
Tiny games and up have certain curious relational characteristics. Specifically, though ⧾_{G} is infinitesimal with respect to ↑ for all positive values of x, ⧾⧾⧾_{G} is equal to up. Expansion of ⧾⧾⧾_{G} into its canonical form yields {0{{0{{0{0G}}0}}0}}. While the expression appears daunting, some careful and persistent expansion of the game tree of ⧾⧾⧾_{G} + ↓ will show that it is a second player win, and that, consequently, ⧾⧾⧾_{G} = ↑. Similarly curious, mathematician John Horton Conway noted, calling it "amusing," that "↑ is the unique solution of ⧾_{G} = G." Conway's assertion is also easily verifiable with canonical forms and game trees.
