The 'Neither Greater-Than Nor Less-Than' symbol (≹) is a mathematical operator featuring a stacked greater-than and less-than sign crossed out with a diagonal slash. In advanced mathematics and order theory, it is used to indicate that two elements in a partially ordered set (poset) are strictly incomparable. While essential for specific mathematical proofs, it rarely appears in standard typography or everyday internet conversation.
