In
signal processing, the
preimage ("before the
fold"/
recto)
function of a
loopstring➿ configuration,
:== the
sequence of
pencils✏️ (ie. set of intermediate
states - to include
SMALL branes and
yesegalo) that are
framed prior to the
determination of an
object's
image. The
preimage is the inverse of an image. (see
random coil)

/// The preimage range is comparable to a denatured protein. Likewise, its domain could be that of subchem.
