OEIS Sequences

a(1)=0; for n>1, a(n) = number of isomeric hydrocarbons of the acetylene series with carbon content n. A642

Number of ways to write n as an ordered sum of 6 prime powers (including 1). A341135

Cardinalities of the sets of fusible numbers obtained at the consecutive steps of their construction as follows. We set S(0) = {0}. S(n+1) is obtained by adding to S(n) the sums (x+y+1)/2 for all x,y from S(n) with the property |x-y| < 1. Then, a(n) is the number of elements in S(n). A343264

Numbers n such that n⁹+9 and n⁹-9 are prime. A239505
