references for Sindx_Cy

[Maximilian Hasler]

Dear Neil and/or associate webmasters,

on page
http://www.research.att.com/~njas/sequences/Sindx_Cy.html#CyclotomicPolynomialsValuesAtX
you could add a reference to the series
A070518-A070527
which gives Phi[n]( a(n) ) for some basic a's, and also the indices
for which this is prime.
It's related to the series I recently submitted, inspired from
http://primes.utm.edu/glossary/page.php?sort=UniquePrime
but I did not realize the presence of this whole series until now.
Thanks,
Maximilian
