Multinorm one tori are stably rational when the gcd d of factor degrees is 1, with a retract-rationality criterion, failure conditions for d>1, and equivalent stable-rationality conditions when splitting occurs over Galois extensions whose groups have cyclic Sylow subgroups or are dihedral.

The rationality problem for multinorm one tori, II
Multinorm one tori are stably rational when the gcd d of factor degrees is 1, with a retract-rationality criterion, failure conditions for d>1, and equivalent stable-rationality conditions when splitting occurs over Galois extensions whose groups have cyclic Sylow subgroups or are dihedral.
