If Clyde hasn't been peeking into Music Theory 101 text (like I have) then
give him a gold star or a cigar.  Upon review, we remember the definition of
an inverted interval is where the top note is moved down an octave or the
bottom note is transposed up an octave.  So the intervals when inverted but
remain "perfect" (ie nothing else) are the 5th and 4th.  The book also gives
two other perfect intervals, the unison and octave.  ---ric
