The critical exponents for the average chirality, beta(d) = 0.90(3), and the chiral susceptibility, gamma(c) = 0.68(6), are determined for the spin-ordering transition in helimagnet Ho. The beta(c) is extraordinarily large and twice higher than the predicted value for the chiral universality class, while the gamma(c) is in agreement with this scenario.
