We use the chiral quark soliton model to estimate masses and widths of the two eikosiheptaplets (27-plets of SU(3) flavor) of spin 3/2 and 1/2 that emerge in the rigid rotator quantization. We use as input: hyperon decays, Theta+ mass and width. While 27_{ 3/2} has small widths (although much larger than the values allowed by the partial wave analysis), 27_{ 1/2} has large decay widths to antidecuplet. However exactly for this decay channels the widths are suppressed in the large N_{ c} limit.
