What is true of it

G♯ Lydian dominant is G♯, A♯, B♯, C𝄪, D♯, E♯ and F♯, and back to G♯.

Its steps are W – W – W – H – W – H – W, where W is a whole step and H a half.

Written correctly it needs 8 alterations, C𝄪 among them. That is what the letters force, and it is also why nobody writes music in this key: the same notes spelled from the other side are easier to read.

On the same tonic, G♯ Lydian differs from it by exactly one note.

Across the first twelve frets of the guitar its notes fall in 43 places, which is what makes a scale a shape rather than a list.
