I am struggling with the notation "=" of the property (a) which concludes to [a]=[m].
shouldn't it be [a]⊆[m], just like [m]⊆M.

What does ##a \in [m]## mean? And what can be said about all elements ##b \sim a## if we use transitivity of ##\sim##?
In retrun, what does it mean for all elements ##c \sim m##?
