InterpretationBox[boxes, expr] is a low-level box construct that displays as boxes but is interpreted on input as expr.
LengthWhile[list, crit] gives the number of continuous elements e_i starting at the beginning of list for which crit[e_i] is True.
MoebiusMu[n] gives the Möbius function \[Mu](n).
Refresh

TagBox
(Built-in Mathematica Symbol) TagBox[boxes, tag] is a low-level box construct that displays as boxes but maintains tag to guide the interpretation of boxes on input.
TakeWhile[list, crit] gives elements e_i from the beginning of list, continuing so long as crit[e_i] is True.
