   • 1905, Royal Irish Academy, Proceedings of the Royal Irish Academy, page 33:

     We must, in short, employ a special bracket for operative relations ; and the square bracket is the most convenient. Hence [a + bβ] x denotes that a + bβ operates on x, and [φ]ⁿ denotes that φ operates on itself n - 1 times.
