First Multiplier Theorem
Let 
be a planar Abelian Difference Set and 
be any Divisor of 
. Then is a numerical multiplierof , where a multiplier is defined as an automorphism 
of 
which takes to a translation 
of itselffor some 
. If is of the form 
for 
relatively prime to the order of , then is called a numerical multiplier.
