Definition.  An "indited set" j^S extends the incidental and extraneous indication of a set into a constant indictment of its entire membership.

j^S = j^{j^s : s C S} = j^{<j, s> : s C S} = <j, {j} x S>.

j \widehat{~} S

& = & j \widehat{~} \{ j \widehat{~} s : s \in S \}

& = & j \widehat{~} \{ (j, s) : s \in S \}

& = & (j, \{ j \} \times S)

Notice the difference between these notions and the more familiar concepts of an "indexed set", "numbered set", and "enumerated set".  In each of these cases the construct that results is one where each element has a distinctive index attached to it.  In contrast, the above indications and indictments attach to the set S as a whole, and respectively to each element of it, the same index number j.
