In his third edition of the Köchel catalogue, he dated it to early 1765 in London, and opined that the incipit showed the influence of J. C. Bach's symphonies.

Bach beginning in this march-like way were written later than
Stirling numbers of the second kind for Stirling numbers of the second kind. The brace notation formula_2 was used by Imanuel Marx and Antonio Salmeri in 1962 for variants of these numbers. This led Knuth to use it, as shown here, in the first volume of "The Art of Computer Programming" (1968). However, according to the third edition of "The Art of Computer Programming", this notation was also used earlier by Jovan Karamata in 1935. The notation "S"("n", "k") was used by Richard Stanley in his book "Enumerative Combinatorics". Since the Stirling number formula_15 counts set partitions of an "n"-element set into "k" parts, the sum
