• Lesser member p of cousin primes (p, p+4) such that (p+1, p+2, p+3) all have the same number of prime divisors (counted with multiplicity).at n=30A094230
• Primes of the form 6n^2 - 2n - 1.at n=29A099007
• Primes arising in A073946.at n=18A113943
• Triangle read by rows: T(n,k) is the number of deco polyominoes of height n with k cells in the second row (0<=k<=n-1; a deco polyomino is a directed column-convex polyomino in which the height, measured along the diagonal, is attained only in the last column).at n=40A134436
• Prime numbers whose hexadecimal representation uses only the digits A,B,C,D,E,F (and not the decimal digits).at n=40A140969
