• Numbers whose base-4 representation contains exactly four 1's and four 3's.at n=12A045133
• a(n) = 6*2^n - 3*n - 5.at n=12A101946
• Combinatorial triangle !n. This table read by rows gives the coefficients of general sum formulas of n-th left factorials (A003422). The k-th row (k>=1) contains T(i,k) for i=1 to 2*k and k=1 to n-2, where T(i,k) satisfies !n = n + Sum_{k=1..n-2} Sum_{i=1..2*k} T(i,k) * C(n-k-1,i).at n=27A102639
• Binomial transform of A109747.at n=13A153732
• Integers of the form 4n+3 for which Sum_{i=1..u} J(i,4n+3) obtains value zero exactly 7 times, when u ranges from 1 to (4n+3). Here J(i,k) is the Jacobi symbol.at n=33A166057
• Number of n X 3 arrays of occupancy after each element stays put or moves to some horizontal or antidiagonal neighbor, without move-in move-out straight through or left turns.at n=3A221933
• T(n,k)=Number of nXk arrays of occupancy after each element stays put or moves to some horizontal or antidiagonal neighbor, without move-in move-out straight through or left turns.at n=18A221937
• Number of 4Xn arrays of occupancy after each element stays put or moves to some horizontal or antidiagonal neighbor, without move-in move-out straight through or left turns.at n=2A221940
• Smallest m such that gcd(A227113(m+1), A227113(m)) = n.at n=37A227289
• Numbers k such that k!6 - 36 is prime, where k!6 is the sextuple factorial number (A085158).at n=24A289700
• Numbers k such that N = k^6 is a twin rank (cf. A002822: 6N +- 1 are twin primes).at n=12A326236
