    I have added some hyperlinks (such as to cofinal) and I have given a size hierarchy to the various brackets in

    {x{0,1}|(x=0)((x=1)p)} \Big\{ x \in \{0, 1\} \Big\vert (x = 0) \vee \big((x = 1) \wedge p\big) \Big\}
        x \in \{0, 1\} 
        (x = 0) \vee \big((x = 1) \wedge p\big)


    Finally (but this concerns not your edits but the decision I had made when creating this entry), I have removed from the entry’s name the last words “of every net” (as they made the title overly long while being essentially redundant).
