OEIS Sequences

A simple grammar: cycles of pairs of sequences. A52823
T(n,k)=Number of -k..k arrays x(0..n-1) of n elements with nonzero sum and with zero through n-1 differences all nonzero. A200165
Triangle read by rows: T(n,k) is the number of non-isomorphic colorings of a toroidal n X k grid using exactly two colors under translational symmetry, 1 <= k <= n. A294684
a(n) = 3·a(n-1)+4 for n > 0; a(0) = 6. A171495
Number of -n..n arrays x(0..4) of 5 elements with nonzero sum and with zero through 4 differences all nonzero. A200168
Numbers n such that the n-th digit (after the decimal point) in the decimal expansion of π are the occurrence of the least significant digit represented by the more significant digits. A201545
Number of connected unlabeled vertex-transitive graphs with n nodes such that complement is also connected. A54917
Number of -5..5 arrays x(0..n-1) of n elements with nonzero sum and with zero through n-1 differences all nonzero. A200162
Achilles numbers - powerful but imperfect: if n = Product(pie_i) then all ei > 1 (i.e., powerful), but the highest common factor of the ei is 1, i.e., not a perfect power. A52486
Triangular numbers whose sum of divisors is an oblong number. A317478
