OEIS Sequences

Consider the Diophantine equation x³ + y³ = z³ - 1 (x < y < z) or 'Fermat near misses'. The values of z (see A050787) are arranged in monotonically increasing order. Sequence gives values of y. A50789

Decimal representation of the diagonal from the origin to the corner of the n-th stage of growth of the two-dimensional cellular automaton defined by "Rule 141", based on the 5-celled von Neumann neighborhood. A286029

a(n) = 6·a(n-2) - a(n-1), with a(0)=1, a(1)=3. A165405

a(n) = 37·2^n-1-1. A171390

Partial sums of the number of active (ON, black) cells in n-th stage of growth of two-dimensional cellular automaton defined by "Rule 51", based on the 5-celled von Neumann neighborhood. A270020

a(n) = 2·a(n-1) + 1 for a(n-1) not prime, otherwise a(n) = prime(n) - 1; with a(1) = 147. A375155

a(n)=(1/2)*Sum{|d(i)-e(i)|} where Sum{d(i)*10ⁱ} is the base 10 representation of n and e(i) are the digits d(i) in nondecreasing order. A37887
