\precneqqThe symbol \precneqq is used in mathematics to denote a negated relation, specifically indicating that one element is not strictly less than another in a partially ordered set. It is a combination of the symbols \prec (precedes) and \neqq (not equal), and is used to express that a certain order relation does not hold between two elements.
Element 'a' does not precede element 'b' in the order relation.
a \precneqq bNeither 'x' precedes 'y' nor 'y' precedes 'z' in the order relation.
x \precneqq y \land y \precneqq zEither 'p' does not precede 'q' or 'q' does not precede 'r' in the order relation.
p \precneqq q \lor q \precneqq r
