It's obviously not for bass guitar and nothing a clef change to treble wouldn't sort out in the lower staff. Do that and the visual joke is blown as you'd then see that the chords in each staff are exactly the same.
The notes are written twice: once in bass clef, once in treble clef. There are only 5 notes.
Whether a 5- or 6- stringed bass guitar can play them as a chord, I didn't check.
