Simple solutions of modified tetrahedron equation are given. These sol
utions are related to the known solutions of the tetrahedron equation.
Each R-matrix contains one (or two) ''spectral'' parameter(s). Using
these simple solutions one gets two (resp. four) parameters commuting
sets of two-layer transfer matrices, the whole number of parameters in
each two-layer transfer matrix being five (resp. ten). (C) 1997 Elsev
