# U+29FE TINY

U+29FE was added to Unicode in version 3.2 (2002). It belongs to the block Miscellaneous Mathematical Symbols-B in the Basic Multilingual Plane.

This character is a Math Symbol and is commonly used, that is, in no specific script.

The glyph is not a composition. It has a Neutral East Asian Width. In bidirectional context it acts as Other Neutral and is not mirrored. In text U+29FE behaves as Alphabetic regarding line breaks. It has type Other for sentence and Other for word breaks. The Grapheme Cluster Break is Any.

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||0|-G} for any game G, whereas miny G (analogously denoted ⧿G) is tiny G’s negative, or {G|0||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||0|-G|||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, 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.
