  We study possibilities to extend the Standard Model (SM) by three flavors of
vectorlike heavy quarks in pseudoreal representation of symplectic hypercolor
gauge group. This extension of SM predicts a rich spectra of heavy composite
hypermesons and hyperbaryons (all of them carry integer spins) including
fourteen pseudo-Nambu--Goldstone states emerging in dynamical breaking of the
global symmetry group of the H-quarks, SU(6), to its Sp(6) subgroup. The
properties of the lightest states depend strongly on the choice of heavy-quark
hypercharges. Our focus is placed on the variants of the model with partially
composite Higgs boson, i.e. the experimentally observed boson is comprised of
the elementary SM Higgs and a mixture of H-hadrons.
