One Hundred Propositional Tautologies (5)

The same like last post, but this time 1500 tautologies, and
these are in the infix form. It is very easy to change prefix
into infix in Newlisp. And vice versa - same function can be
used for changing infix to prefix. But, tautologies are great.

```(set 'infix<->prefix
(lambda(L)
(cond ((symbol? L) L)
((= (length L) 2) (map infix<->prefix L))
((= (length L) 3) (let((L1 (map infix<->prefix L)))
(list (nth 1 L1) (nth 0 L1) (nth 2 L1))))))) ```
