Two rotations (of an object with four or more dimensions) that happen simultaneously along two different two-dimensional planes without interfering with each other.

Examples

“This matrix form makes it clear that a double rotation can be thought of as two simultaneous simple rotations: in this case a rotation of angle #92;alpha#92;in(-#92;pi,#92;pi#93; in the x–y plane, and one of angle #92;beta#92;in(-#92;pi,#92;pi#93; in the (z–w)^([sic]) plane.”
