Expression of type Forall

from the theory of proveit.logic.sets.enumeration

proveit.defaults.automation = False # This will speed things up.
proveit.defaults.inline_pngs = False # Makes files smaller.

# build up the expression from sub-expressions

# Show the LaTeX representation of the expression for convenience if you need it.
