What you mean when you claimed that 3^^4 & 3 equivalent to 3^7625597484987 & 3 array? I can agree with it, because I decided to defined when expression to the left to the & sign is a number (without X's), it should be solved as linear array. So 3^^4 & 3 is really {3,3,3,...,3,3,3} (with 3^^4 3's), but X^^4 & 3 is much larger. Are you aware that X^^4 & 3 (not equal to) X^7625597484987?
