Abstract:
<p>
Bell-type _equalities_ are derived for the Leggett-Garg proposal for a
SQUID experiment on the assumptions of macroscopic realism (MR)
and noninvasive measurability (NIM). Equalities of this sort have not
previously been presented.  It is shown that there are 18 such equalities. 
These equalities put stronger constraints on the consequences of (MR) 
and (NIM) than the corresponding inequalities.
