Right! Let us try and use these various expressions and, in future, the use will cut very sharply. As a matter of fact, we need both (so to say) multi-dimensional logos and ASCII type sequential special characters. Actually, both "floating point" and "tetrational notations", in a sequential ASCII notation, can be written as N = p.b^n and N = p*b#n, with unabiguous meanings for ^ (exponentiation sign) and # (tetration sign), supposing to have stated that operations "^" and "#" have priority as regard to "." and "*" and that "*" refers to base b (!!!). The problem is the meaning here of "*", which will be new, specific, uncomplete and confusing. Actually, it is uncomplete because it must be referred to base b and should be written as "*\super scripted b". In fact, "x(*\b)y" is a ternary operation. A ... provisional mess. I should try to avoid T and/or S, which may remind other things. Finally, I like very much my "box notation", absolutely not ambiguous, but non-sequential and too new. We shall see.
