What ⧿ means
For a game G, Miny is the negative of Tiny applied to G. Combinatorial game theory studies two-player positions where each side can have different legal moves.
John Conway introduced Tiny and Miny in his book On Numbers and Games (1976); the game-theory book Winning Ways (1982) developed the subscript notation, with small lowered labels.
