 OFFSET 1,21 COMMENTS For the definition of k-th width of the symmetric representation of sigma(n) see A249351. Row n list the first n terms of the n-th row of A249351. It appears that the leading diagonal is also A067742 (which was conjectured by Michel Marcus in the entry A237593 and checked with two Mathematica functions up to n = 100000 by Hartmut F. W. Hoft). For more information see A237591, A237593.
