The shape nearest the nut leaves the G course open and takes the rest at fret 4, reaching across 5 frets. F falls on the A course. It sounds from G2 up to Ab4.
Octave Mandolin is strung in four courses of two, so each stopped note here sounds as two — which is why the shape rings thicker than the same grip on a single-strung instrument.
