In mathematics, the spinor genus is a classification of quadratic forms and lattices over the ring of integers, introduced by Martin Eichler. It refines the genus but may be coarser than proper equivalence.
lattices are in the same spinorgenus, and lattices in the same spinorgenus are in the same genus. The number of spinor genera in a genus is a power of two...
