Description: Alternate definition of the coelement equivalence relation predicate: a coelement equivalence relation is an equivalence relation on coelements. Other alternate definitions should be based on eqvrelcoss2 38601, eqvrelcoss3 38600 and eqvrelcoss4 38602 when needed. (Contributed by Peter Mazsa, 28-Nov-2022.) |
