OEIS Sequences

Let p = n-th prime == 7 mod 8; a(n) = sum of quadratic residues mod p that are > p/2. A282040

a(n) is the smallest multiple of n such that a(n) mod 100 = n and S(n)=n where S(n) is the sum of the base-ten digits of n, or 0 if no such a(n) exists. A75154

a(n) is the smallest multiple of n such that a(n) ends with n and S(a(n))=n where S(m) is the sum of the base ten digits of m, or 0 if no such a(n) exists. A187924

a(n) is the number of squarefree composite k with lpf(k) = prime(n) such that m <= ω(k), where lpf = A020639, m = floor(log k / log lpf(k)), and ω = A001222. A377793
