[seqfan] Error in A180269 Primes of the form 3^3+3*n+1

[Jonathan Post]

A180269 Primes of the form 3^3+3*n+1.
But the PARI seems to be for the formula 3^k+3*k+1 instead.
The formula as given in the seq's title is equivalent to "Prtimes of
the form 27 + 3*n + 1" hence "primes of the form 3*n + 28"
which would begin 31, 37, 43, 61, 67, 73, 79, 97, 103, 109, 127, 139, 151, ...
which is A002476  Primes of form 6n + 1 for n>3
or A002476(n+3)
unless I'm also making an elementary mistake.
