A♯ Diminished
A♯ · B♯ · C♯ · D♯ · E · F♯ · F♯♯ · G♯♯
The whole-half diminished scale alternates whole and half steps for eight notes, so A♯ Diminished is perfectly symmetrical and repeats every minor third. Play it over a diminished seventh chord and every chord tone is covered. Its symmetry means one fingering shifts up in minor thirds indefinitely, which jazz and fusion players exploit for long, sequenced lines.
