The density of never changed opinions during the Sznajd consensus-finding
process decays with time t as . We find
for a chain, compatible with the exact Ising result of
Derrida et al. In higher dimensions, however, the exponent differs from the
Ising θ. With simultaneous updating of sublattices instead of the
usual random sequential updating, the number of persistent opinions decays
roughly exponentially. Some of the simulations used multi-spin coding.
