I suggest that those notations are declared to be the *official* OEIS 
notation (prime(.) already is, see spelling and notation in the index) 
at a suitable place of an OEIS page (help file, index, ...).

Well, "... there is some controversy regarding the notation" (Leroy 
Quet). Therefore deviations can be allowed, but only if an explanatory 
note is included.
