 OFFSET 0,4 COMMENTS Left column = odd-indexed Fibonacci numbers prefaced with a 1. Right border = A007051 shifted. Row sums are A007051. LINKS FORMULA Let M = an infinite lower triangular matrix with odd-indexed Fibonacci numbers in every column prefaced with a 1: (1, 1, 2, 5, 13, 34, ...). Q = an infinite lower triangular matrix with A007051 prefaced with a 1 as the main diagonal: (1, 1, 2, 5, 14, 41, 122, 365, 1094, ...); and the rest zeros. A147292 = M * Q EXAMPLE First few rows of the triangle = 1; 1, 1; 2, 1, 2; 5, 2, 2, 5; 13, 5, 4, 5, 14; 34, 13, 10, 10, 14, 41; 89, 34, 26, 25, 28, 41, 122; 233, 89, 68, 65, 70, 82, 122, 365; 610, 233, 178, 170, 182, 205, 244, 365, 1094; 1597, 610, 466, 445, 476, 533, 610, 730, 1094, 3281; 4181, 1597, 1220, 1665, 1246, 1394, 1586, 1825, 2188, 3281, 9842; 10946, 4181, 3194, 3050, 3262, 3649, 4148, 4745, 5470, 6562, 9842, 29525; ... Row 4 = (13, 5, 4, 5, 14) = termwise products of (13, 5, 2, 1, 1) and (1, 1, 2, 5, 14).
