(Remark: These tiny urls are nice, but can be quite annoying when they point to a website that re-arranged its directory structure - with tinyurls ultra-efficient and discreet forwarding system you sometimes can't get the slightest info about where/what you had been pointed to and try to find it "by hand"...Â [this happened to me a few days ago - but I forgot where & what is was about...])
p=2 : A006254 Numbers n such that 2n-1 is prime.
p=3 : A002504 numbers such that 1+3x(x-1) is (a "cuban") prime.
p=5 : A121617 Nexus numbers of order 5 (or A022521[n-1] = n^5 - (n-1)^5) are primes.
p=7 : A121619 Nexus numbers of order 7 (A022523[n-1] = n^7 - (n-1)^7) are primes
p >= 11 seems not yet there, so Mike could enter his numbers into OEIS, starting there !
