OEIS Sequences

Barely abundant numbers: abundant n such that σ(n)/n < σ(m)/m for all abundant numbers m<n, σ(n) being the sum of the divisors of n. A71927

Numbers n such that n/6 and prime(n)+/-n are all primes. A105550

Solution of the complementary equation a(n) = a(n-1) + a(n-3) + a(n-4) + b(n-1), where a(0) = 1, a(1) = 2, a(2) = 3, a(3) = 4, b(0) = 5, b(1) = 6, b(2) = 7, b(3) = 8, and (a(n)) and (b(n)) are increasing complementary sequences. A295757

a(n) = 42*(n+1)*binomial(n+6,10). A27822
