 OFFSET 1,3 COMMENTS In the notation of Nemirovsky et al. (1992), a(n), the n-th term of the current sequence is C_{n,m} with m=1 (and d=4). Here, for a d-dimensional hypercubic lattice, C_{n,m} is "the number of configurations of an n-bond self-avoiding chain with m neighbor contacts." (For d=2, we have C_{n,m=1} = A033155(n) while for d=3, we have C_{n,m=1}=A047057(n).) These numbers are given in Table I (p. 1088) in the paper by Nemirovsky et al. (1992). - Petros Hadjicostas, Jan 04 2019 LINKS Table of n, a(n) for n=1..15. A. M. Nemirovsky, K. F. Freed, T. Ishinabe, and J. F.
