A. Polyconic does NOT have standard parallels.
ALL parallels are "standard" in the polyconic.
B. Brazil uses the Lallemand Polyconic; not the
standard "American Polyconic."
C. The equations are DIFFERENT for Brazil.
D. Check the specifications for the
International Map of the World - THAT
is what Brazil uses - Lallemand.
