Percolation has a singularity at the critical point and many properties behave as of a power-law with formula_5, near formula_2. Scaling theory predicts the existence of critical exponents, depending on the number "d" of dimensions, that determine the class of the singularity. When these predictions are backed up by arguments from conformal field theory and Schramm–Loewner evolution, and include predicted numerical values for the exponents. The values of the exponents are given in and. Most of these predictions are conjectural except when the number of dimensions satisfies either or . They include:
