Fig. 1 — nothing to hold

guitar chord

D♯5

D♯1A♯5

Root and fifth, no third at all — neither major nor minor, which is the point.

Written the other way round it is E♭5 — the same twelve keys on a piano, a different piece of notation.

What is true of it

D♯5 is D♯ and A♯ — 1 and 5 counted from D♯.

No fingering of D♯5 fits a hand on the guitar: inside four frets, with the strings that sound next to each other and the root underneath, there is nothing to hold.

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.
