The Somos-6 sequences of rank 3

Avdeeva M.O.

2018, issue 1, Ñ. 3-8

Nondegenerate Somos-4 sequences have rank 2. The rank of the product of two such sequences does not exceed 4, and then the Somos-2k sequences with k = 2, 3, 4 arise. In this paper we construct pairs of Comos-4 sequences such that them products are the Comos-6 sequences.
