Fundamental Theorem of Genera
Consider 
proper equivalence classes of forms with discriminant 
equal to the field discriminant, then they can besubdivided equally into 
genera of 
forms which form a subgroup of the proper equivalence class groupunder composition (Cohn 1980, p. 224), where 
is the number of distinct prime divisors of . This theorem was proved byGauß 
in 1801.
