COMMENTS
| Is this a duplicate of A035095? [From R. J. Mathar (mathar(AT)strw.leidenuniv.nl), Dec 13 2008]
For the first 5*10^6 terms, a(n) = A035095(n). - Donovan Johnson, Oct 21 2011

|
|
FORMULA
| a[n] = Min{m : Mod[Phi[m], p(n)] = 0} = Min{m :Mod[A000010(m), A000040(n)] = 0}
|
|
|
EXAMPLE
| All terms seem to be primes of the form a[n]=k*p[n]+1 with various values of k.
