The third replaced by the fourth, which leans on the third it is standing in for.

Written the other way round it is F♯sus4 — the same twelve keys on a piano, a different piece of notation.

What is true of it

G♭sus4 is G♭, C♭ and D♭ — 1, 4 and 5 counted from G♭.

These are also the notes of Bsus2/G♭. Which name is right depends on what is underneath and what came before — the notes alone do not decide.

The easiest of the 3 fingerings below is x674: 3 fingers, held at the 4th fret.

None of them uses an open string, so this chord moves up the neck unchanged — the same shape 1 fret higher is the chord a semitone above.

1 string stays silent.

The brass dots are G♭, the root. Everything else is a chord tone with its degree printed in it.

An inversion is the same chord with a different note lowest. The name changes to a slash name because the bass is what a listener hears as the foundation.
