distinct_subset_existence(self, elems, \*\*defaults_config)

Assuming the cardinality of the domain can be proven to be >= 2, proves and returns that there exists distinct elements in that domain.

Keyword arguments are accepted for temporarily changing any of the attributes of proveit.defaults.

latex(self, fence=False)

Return a latex-formatted representation of the Expression. The kwargs can contain formatting directives (such as ‘fence’ used to indicate when a sub-expression should be wrapped in parentheses if there can be ambiguity in the order of operations).

string(self, fence=False)

Return a string representation of the Expression. The kwargs can contain formatting directives (such as ‘fence’ used to indicate when a sub-expression should be wrapped in parentheses if there can be ambiguity in the order of operations).
