Palindrone

So about 6 months ago I made a list of numbers between 100000 and 999999 that are prime in both lexiconographical order.

here's a sample:

384187, 384203, 384253, 384257, 384301, 384359, 384383, 384473, 384497, 384581, 384589, 384611, 384673, 384737, 384751, 384821, 384841, 384889, 384913, 384961, 385039, 385079, 385087, 385159, 385171, 385223, 385249, 385267, 385291, 385321, 385331, 385393, 385471, 385621, 385709, 385741, 385811, 385837, 385843, 385901, 385991, 386017, 386041, 386119, 386149

The full list can be found here:

I don't recall how I isolated this list, but here it is none the less.
Yes I know that Palindrome isn't spelt with an "n"
And no I didn't know what lexiconographical even meant until someone on the net told me.

Usefulness: 0.003
Fun: 2.3
