• G.f. satisfies A(x) = 1 + x*cycle_index(G,A(x)) where G = tetragonal pyramid group of order 8 with cycle index (z1^5+2*z1*z4+3*z1*z2^2+2*z1^3*z2)/8.at n=9A036784
• Primes whose digits can be rearranged to give the initial terms of the decimal expansion of Pi.at n=10A052493
• Primes p such that sum of squares of even-position digits equals the sum of squares of odd-position digits of p.at n=11A076168
• Triangle T, read by rows, such that T(n,k) equals the (n-k)-th row sum of T^k, where T^k is the k-th power of T as a lower triangular matrix.at n=56A091351
• Row sums of triangle A091351, in which the k-th column lists the row sums of the k-th power of A091351 (when considered as a lower triangular matrix).at n=9A091352
• Triangle, read by rows, such that T(n,k) equals the k-th term of the convolution of the (n-1)-th diagonal with the k-th row of this triangle.at n=64A098446
• Triangular matrix T, read by rows, that satisfies: SHIFT_LEFT_UP(T) = T^2 - T + I, or, equivalently: T(n+1,k+1) = [T^2](n,k) - T(n,k) + [T^0](n,k) for n>=k>=0, with T(0,0)=1.at n=67A104445
• Rectangular table, read by antidiagonals, defined by the following rule: start with all 1's in row zero; from then on, row n+1 equals the partial sums of row n excluding terms in columns k = m*(m+1)/2 - 2 (m>=2).at n=56A125781
• Concatenate the terms of A027750 (omitting spaces and commas), chop into blocks of length 5, then omit any leading zeros.at n=9A362446
