OEIS Sequences

a(n) and floor(a(n)/8) are both squares; i.e., squares that remain squares when written in base 8 and last digit is removed. A55872

Square array T(n,k), n >= 1, k >= 1, read by antidiagonals, where T(n,k) = sqrt( ∏_a=1..n ∏_b=1..k (4·sin((2·a-1)*π/(2·n))² + 4·sin((2·b-1)*π/k)²) ). A341533
