[seqfan] Re: Sequence contains only three elements 2, 4 and 6

[Tw Mike]

Dear Andrew,

Thanks for your searching method,it's powerful.
There's another seq [6]:
numbers n that n/2 is prime, n and 2n between twin prime.
a[0] is 6, a[1] maybe extreme large or doesnt exist.
Supose OEIS has advanced web search such as a[0] == 6 and a[1] > 1e6.

Yours mike,
