Appears in sequences

• Expansion of 1/((1-x)*(1-2*x)*(1-5*x)*(1-7*x)).at n=5A021124
• When this sequence is interleaved with its first differences and the resulting sequence is divided into blocks of 10 digits, each block contains 10 distinct digits. Each term is chosen to be the smallest that satisfies this property.at n=17A101246
• Triangle t(n,k) read by rows: fibonomial ratios c(n)/(c(k)*c(n-k)) where c are partial products of a generalized Fibonacci sequence with multiplier m=4.at n=38A172349
• Triangle t(n,k) read by rows: fibonomial ratios c(n)/(c(k)*c(n-k)) where c are partial products of a generalized Fibonacci sequence with multiplier m=4.at n=42A172349
• Number T(n,k) of equivalence classes of ways of placing k 4 X 4 tiles in an n X n square under all symmetry operations of the square; irregular triangle T(n,k), n>=4, 0<=k<=floor(n/4)^2, read by rows.at n=43A236757
