Symphony, K. 19b (Mozart) symphonies K. 16 and K. 19 (strings, 2 oboes, and 2 horns). 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. His remarks were copied unchanged by the sixth edition of the Köchel catalogue. Neal Zaslaw agreed that the opening was characteristic of J. C. Bach in his book "Mozart's Symphonies", but questioned if this was a legitimate method of dating works, given that the seven symphonies of J. C. Bach beginning in this march-like way were written later than
Stirling numbers of the first kind Stirling numbers of the first kind In mathematics, especially in combinatorics, Stirling numbers of the first kind arise in the study of permutations. In particular, the Stirling numbers of the first kind count permutations according to their number of cycles (counting fixed points as cycles of length one). The original definition of Stirling numbers of the first kind was algebraic. These numbers, usually written "s"("n", "k"), are signed integers whose sign, positive or negative, depends on the parity of "n" − "k". Afterwards, the absolute values of these numbers, |"s"("n", "k")|, which are known as unsigned Stirling numbers of the
