 OFFSET 1,4 COMMENTS In the notation of Nemirovsky et al. (1992), a(n), the n-th term of this sequence is p_{n,m}^{(l)} with m=1 and l=3. These numbers are given in Table II (p. 1093) in the paper. This sequence can be used for the calculation of sequence A047057 via Eq. (5) in the paper by Nemirovsky et al. (1992). (Note that, by equations (7b) in the paper, p_{n,m=1}^{(1)} = 0 for all n >= 1. Also, p_{n,m=1}^{(2)} = A038747(n) for n >= 1.) - Petros Hadjicostas, Jan 04 2019 LINKS A. M. Nemirovsky, K. F. Freed, T. Ishinabe, and J. F.

A. Sloane, May 02 2000 EXTENSIONS The first three 0's in the sequence were added by Petros Hadjicostas, Jan 04 2019 to make it agree with Table II (p. 1093) and Eq. (5) (p. 1090) in the paper by Nemirovsky et al. (1992). STATUS approved
