What is true of it

D♯6 is D♯, F𝄪, A♯ and B♯ — 1, 3, 5 and 6 counted from D♯.

F𝄪 is a double sharp, and it has to be: every letter from D♯ upwards is used once, so the 3 cannot be written any other way.

These are also the notes of Cm7/D♯. Which name is right depends on what is underneath and what came before — the notes alone do not decide.

On an instrument that cannot reach all 4, the 5 goes first, in that order.

The easiest of the 5 fingerings below is xx1013: 3 fingers, held at the 1st fret.

1 of them use open strings, which is what makes a shape quiet to change to.

1 of the 5 need a barre.

It leaves out the 5. 6 strings cannot carry 4 notes, and the 5 is the one this chord can lose without changing what it is.

2 strings stay silent.

The brass dots are D♯, 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.
