The standard grips this chord is usually shown with.
Ebmaj7#5 is Eb, G, B and D — Ebmaj7 with the fifth raised a semitone.
It sounds weightless, with no pull in it. Unlike an aug7 there is no flat seventh dragging it anywhere, so it colours a tonic rather than replacing it with a dominant.

| Eb | G | B | D |
|---|---|---|---|
| 1 | 3 | ♯5 | 7 |
Tonic — the lydian augmented sound.
Also written EbM7#5, EbΔ7#5, Eb+M7 or Ebmaj7(#5). The same chord either way; which spelling you meet depends on who wrote the chart.
Ebmaj7#5 in 2nd inversion puts B in the bass instead of Eb, the 5th of the chord. The notes are the same; what changes is what the bass line does, which is most of why you would reach for it — it lets the lowest voice move by step where the root would have jumped.
