| Theorem | un0.1 45318 |
⊤ is the constant true, a tautology (see df-tru 1562). Kleene's
"empty conjunction" is logically equivalent to ⊤. In a virtual
deduction we shall interpret ⊤ to be the
empty wff or the empty
collection of virtual hypotheses. ⊤ in a
virtual deduction
translated into conventional notation we shall interpret to be Kleene's
empty conjunction. If 𝜃 is true given the empty collection
of
virtual hypotheses and another collection of virtual hypotheses, then it
is true given only the other collection of virtual hypotheses.

the Metamath proof of suctrALT 45365 using completeusersproof, which is
verified by the Metamath program. The proof of

If a singleton is a subclass of another class, then the singleton's

right-to-left implication of the biconditional snss 4742.
The proof of
this theorem was automatically generated from snsslVD 45368 using a tools

non-virtual deduction form and minimizing it. (Contributed by Alan

Virtual deduction proof of sstr 3944, transitivity of subclasses, Theorem
6 of [Suppes] p. 23. This theorem was
automatically generated from
sstrALT2VD 45373 using the command file
translate_without_overwriting.cmd . It was not minimized because the
automated minimization excluding duplicates generates a minimized proof
which, although not directly containing any duplicates, indirectly
contains a duplicate. That is, the trace back of the minimized proof
contains a duplicate. This is undesirable because some step(s) of the
minimized proof use the proven theorem. (Contributed by Alan Sare,
