guitar chord
F♯sus2
The third replaced by the second. Nothing in it decides between major and minor.
Written the other way round it is G♭sus2 — the same twelve keys on a piano, a different piece of notation.

What is true of it
F♯sus2 is F♯, G♯ and C♯ — 1, 2 and 5 counted from F♯.
These are also the notes of C♯sus4/F♯ and D♭sus4/F♯. Which name is right depends on what is underneath and what came before — the notes alone do not decide.
The easiest of the 5 fingerings below is xx4122: 4 fingers, held at the 1st 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.
2 of the 5 need a barre.
2 strings stay silent.
Where its notes are on the neck
The brass dots are F♯, 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.
