• Consider the Diophantine equation x^3 + y^3 = z^3 + 1 (1 < x < y < z) or 'Fermat near misses'. Sequence gives values of z in monotonic increasing order.at n=28A050791
• Numbers n such that 243*2^n-1 is prime.at n=47A050880
• a(0)=1, a(m+1) = Sum_{k=0..m}[a(k)^2 * a(m-k)^2].at n=5A053294
• Strictly superdiagonal compositions: compositions (p1, p2, p3, ...) of n such that pi > i.at n=44A238874
• Number of (n+2)X(2+2) 0..2 arrays with every consecutive three elements in every row, column and nw-se diagonal having exactly two distinct values, and new values 0 upwards introduced in row major order.at n=3A252946
• Number of (n+2)X(4+2) 0..2 arrays with every consecutive three elements in every row, column and nw-se diagonal having exactly two distinct values, and new values 0 upwards introduced in row major order.at n=1A252948
• T(n,k)=Number of (n+2)X(k+2) 0..2 arrays with every consecutive three elements in every row, column and nw-se diagonal having exactly two distinct values, and new values 0 upwards introduced in row major order.at n=11A252952
